Current LSR Material Trends in the Molding of Medical Devices

For many years, liquid silicone rubber (LSR) has been used in a range of medical devices—from seals, plungers, and gaskets in implanted and non-implanted devices, to buffering for lung catheters, where soft LSR prevents tearing of delicate lung tissue as the catheter is inserted, to providing dampening for top housing covers on devices.
LSR cures faster than traditional rubber materials and offers properties well-suited for use in medical devices, among them heat-resistance, extreme low-temperature flexibility, chemical resistance, biological inertness, and an intrinsic capacity for reducing friction. LSR also cures completely and quickly, which is especially critical for implanted devices because the device will not leach chemicals and cause potential adverse reactions. In many cases, this has led to LSR replacing latex, a material long used in the medical industry, which does not fully cure during production and can lead to adverse reactions in patients.
In addition, because LSR degrades only at very high temperatures—higher than most other polymers can survive—LSR can tolerate sterilization processes, further increasing its application in medical uses.
While other soft materials, such as thermoplastic elastomers (TPE), duplicate some of its characteristics, LSR offers a unique combination of biocompatibility, resistance to extreme temperature, durability, design flexibility, and moldability. LSR has also continued to evolve, offering even more capabilities.
Designers of new devices routinely specify LSR in their designs. As a result, suppliers of LSR have had to respond to the challenges of these new and often more complex designs by developing new formulations. In turn, as designers have responded by specifying the new formulations in new and more complex designs. Injection molders have also had to adapt to new material performance and new designs with enhanced molding capabilities. The result of all this interaction has been a continuous evolution of LSR formulations and applications.
New Materials
The development of new LSR formulations is ongoing. These new formulations are often the result of new challenges in device designs, but suppliers of LSR are also continually working to develop new formulations that offer new advantages to device designers. The benefits offered by these new formulations include higher tear strength, giving devices wider applications and a longer working life; a longer shelf life, which benefits molders by reducing the waste involved in discarding excess LSR inventory past its use-by date; longer pot life (the time following mixing during which LSR can be molded) that gives molders more molding flexibility; and higher levels of elongation, creating greater part flexibility.
These expanded features enable molders to meet the challenging geometries that often come with new device designs, as well as create greater flexibility for designers. Essentially, new materials with new performance parameters create opportunities for innovation. But new materials also affect the practical applications of the devices themselves.
It is critical for device manufacturers and designers to make the effort to be aware of new materials being developed and the advantages they offer. Too often, companies tend to stay with the materials that have worked in the past and that have already been through the time-consuming approval process. Manufacturers need to stay connected with suppliers to explore the new materials that are continually being developed.

New Demands, New Devices
The medical device marketplace is a fast-changing one, and new technology and new applications are requiring new designs that affect the evolution of LSR formulations. New device materials require improved characteristics such as softness, stretchability, resiliancy, and durability.
To respond to ever-changing market trends and needs, materials suppliers continue to innovate to close need gaps. For example, materials with low durometers, high elongations, and increased tear strengths are required to meet the needs of current and upcoming medical devices. LSR molders are anticipating the needs of future medical equipment and continue to improve their manufacturing capabilities.The following are among the trends they are accommodating:
  • Devices are continually becoming both smaller and more intricate. This is especially true of wearable and implantable devices, which are growing in both number and capability. This trend requires new LSR formulations that enhance LSR’s flexibility, enabling molders to extract products successfully from complex molds with undercuts.
  • As wearable devices increase, these flexible devices require softer LSR formulations that enable the device to work as the patient moves, without loss of function and with minimal patient discomfort.
  • Today’s wearable devices also often include wireless electronic reporting functions that require batteries to operate. LSR overmolding on these devices must be completed at lower temperatures (high temperatures tend to damage smaller batteries). This is requiring the development of LSR that cures at lower temperature, which is currently ongoing.
  • There is continual pressure for medical devices, especially those being developed for home or on-the-go use, to be even smaller, to make life easier for patients, and to provide more detailed monitoring and data gathering. This, in turn, makes new demands on device designers, LSR suppliers, and molders, who will need to work together to meet the challenges.
The demands created by each new medical device design may require a new LSR formulation. As these new formulations come into use, they add to the growing variety of LSR formulations available for designers to incorporate into their new designs.
New Molding Challenges
Just as material evolution often responds to design trends, LSR molding often responds to the development of both new designs and the new formulations developed for use with them. Smaller and more intricate device designs require different molds and molding techniques, and the proliferation of wearable devices and those incorporating electronic communication features add to that need to adapt.
As a result, manufacturers are turning to the molders that they know have the expertise and equipment to meet their specific molding needs. In addition to keeping abreast of the techniques for molding these new devices, molders that can meet these new demands should keep their customers and potential customers advised of their updated capabilities.
Another new development in the molding industry is the prospect of creating devices that incorporate LSR using 3D printing. A challenge that has plagued molders and device manufacturers for years is how to produce prototype devices for approval quickly and cost effectively. This has traditionally been done with one- and two-cavity molds and, more recently, with aluminum molds. But the ability to produce a prototype device in small numbers using 3D printing would completely eliminate the need for a mold, reducing delivery time and cost, and making modifying and producing second-stage prototypes simpler and less costly.
There is also the potential with 3D printing to produce personalized devices for individual patients tailored to their unique medical and physical requirements. LSR formulations developed for 3D printing already exist, but material suppliers are currently working to reduce cure times in order to make the process practical. Meanwhile, forward-thinking molders are becoming familiar with 3D printing technology and evaluating its capability and its limitations prior to adding it to their capabilities.
The Regulatory Scene
All developers and users of medical devices, including those that incorporate LSR, need to be aware of changing regulatory requirements, both those affecting material quality standards and device (and device part) traceability. For example, current regulations (21 CFR 821) now require medical devices to include unique device identifiers (UDI), which could include electronic signature chips on certain individual devices, to facilitate track-and-trace requirements and potential recalls. It is anticipated that future requirements may also require electronic identification of individual device parts as well.
In the recent past, companies introducing new devices have often registered them first with regulatory bodies in the EU, where registration has been less costly and less time-consuming. That is beginning to change, as the EU has become both more costly and paperwork-intensive. We may now see it become more practical for companies to register new devices first with FDA.
Looking Forward
Where is the evolution of LSR use—for molders, formulators, and especially designers and device engineers—headed in the coming years? New formulations will no doubt continue to open new doors for designers and create new molding challenges for molders. In turn, new applications for medical devices will raise new challenges for manufacturers, molders, and material suppliers, especially as wearable and implanted devices increase, become even smaller, and take greater advantage of wireless technology to communicate data.
A major advancement in the LSR arena is a multicomponent system that gives molders flexibility and enhanced control related to cure kinetics. This system approach enables molders to select and optimize the cure speed for part size and dimension, reducing cure time by up to 60%. This can also provide improvements in low-temperature cure applications when overmolding electronic, plastic, and active ingredient applications. As molders know, cure time is the largest part of LSR molding cost, and this would significantly reduce that cost.
LSR suppliers also see greater opportunities for formulations with lower durometers that result in softer surfaces, especially in providing better performance and greater comfort to patients in wearable devices. This is still a solution that formulators are working on. Current lower durometer materials face problems in situations where repeated use is required, for example, because they pick up surface materials that change their surface softness. New formulations may be able to change this.
Another ongoing goal is to develop LSR materials that can be produced more quickly, at lower temperatures, and at lower cost. These new materials could reduce the overall cost of molding as well as support further miniaturization and the molding of disposable devices.
These innovations are being actively explored by leading silicone suppliers and medical device manufacturers. All players in the industry—manufacturers, molders, and material suppliers—should work together to cooperate to lead this continuing growth. Each will have specific needs as these developments take place, and each brings different skills and experience to the table to make them happen. But all players benefit from the result, and most importantly, patients benefit from the collaboration.

This article mentions very important tips to select good plastic molding equipment machine, but we think the tips to select good plastic mold is also a key to molding success.  Intertech can help customer to fulfill this plastic mold making and molding success.  Welcome to talk to Intertech !


Though selecting the right molding equipment can be tough, it is the most important step one can do. This can be the only way to making quality parts every time and beneficially. With the right choice of equipment, a facility is guaranteed a smooth operation where they will not need to hike their product cost. Besides, good molding equipment is more effective and convenient thus it can make a facility more competitive. As a result, the rates of sales can possibly popup leading to great earning. A company can then be recognized as a quality manufacturer. By selecting quality equipment for molding, an individual can be rest assured of security regarding the potential clients where they can stay for long.
Here is a short guide to purchasing quality equipment for molding.

Consider The Type Of Plastic You Want To Mould

Initially, you must know the type of plastic you want to mold before selecting a molding machine. Most molding machines work with specific plastics thus if you feed in it a different type, it can only lead to problems. For instance, the machine can become much slower, with bad quality results. In the process, this can lead to both the machine and mold damage. The size and weight of the mold is also an important factor to consider. Knowing how to determine the correct part is the key to find the best injection unit size and machine type.

Select Machine Type

Currently, there are about three types of injection molding machine available. According to MoldChina, a plastic injection mold company in china, they vary and are in different designs. These includes fully hydraulic, fully electric, and a combination of the two known as the, hybrid. The hydraulic machine contains clamps, hydraulic pumps, and accumulators. Electric ones are, however, with motors that are powered by electric thus they are very energetic. For this reason, they are suitable for molding medical devices. Finally, the hybrid plastic contains both these features where it can use both the hydraulic drive and the electric drive.

Calculate Clamp Tonnage Requirements

There are numerous ways of calculating the required clamp tonnage requirement for the injection molding machine. These include, by the computer simulation software, experience, and many more. The simple way, in this case, is by checking factors such as, plastic material, length by width by height, projected area average wall section, gate position, maximum flow length from the gate, and the number of cavities in the mold.

Calculate The Injection Unit Size

For a suitable unit selection, there are many facts that you must be familiar with. These include the plastic material, cycle time, cooling time, peak injection pressure requirement, plasticizing rate and injection rate among others. In many occasions, there are 2 injection units for one to choose from with the same number of different screws and barrel assemblies. If you can consider these factors and do the right calculation, then there is no, doubt, you will choose the right and reliable machine for your molding tasks.
In summary, the molding tactics are different since different products are made differently. For instance, there are molding types that are for hollow plastics while others are for completing the process to give a finish. So, in an event where you are selecting an equipment for molding, it is important to consider the abilities of techniques with regard to the desired final product.

LSR in the spotlight of NPE 2018 Glad to know LSR is widely applied in many industries now. In NPE 2018, we can see many machine manufacturers has developed advanced molding technology now.  Glad to say that Intertech is a professional and knowledgeabl mould supplier in making liquid silcione mold in Taiwan.  Welcome to send your LSR mold and molding project to us !

http://www.taiwanmoldmaker.com/product/liquid-silicon-rubber-mold


Undiminished interest in liquid silicone rubber (LSR) will be evident in molding demonstrations by at least nine injection machine builders.
Arburg (Booth W1325) will show two examples of two-shot LSR/LSR molding—one producing a watch strap in two colors and durometers, and another making a dual-durometer membrane for valves used in medical and automotive applications. The latter will use Arburg’s 0.1-oz micro-injection unit with a 0.3-in. screw diam. to produce one shot of 0.0018 oz, followed by a second shot from a servo-electric injector from Kipe Molds.

 
The largest press from Boy Machines (Booth W2503), Boy 100E (110 tons) will produce LSR protective sleeves for cable ends in a 128-cavity mold from Elmet.
Engel (Booth W3303) is showing for the first time a particularly complex LSR application—automotive headlight lenses with light guides. They will run on a 120-ton, tiebarless, all-electric e-victory machine with a metering/pumping system and two-cavity mold, both from ACH solution in Austria. The mold uses a new ServoShot cold-runner valve-gate system with valves that are pneumatically actuated but the pin strokes are set electrically. All the valve gates open together, but varying the pins’ open positions adjusts the flow through each valve gate. Parts will be checked via integrated camera inspection and will be weighed individually. The ServoShot software then will adjust the pin openings to balance the fill and equalize the weights in the cavities. The entire cell, including LSR dosing, is handled by the Engel CC300 controller.
 
KraussMaffei (Booth W403) will mold LSR medical dosing caps, or “duckbills,” on its PX 51-55 SilcoSet all-electric machine.
Maruka (Booths W1103, W911) will mold LSR magnifiers on a Toyo Si-110-6.
 
 
Milacron (Booth W2703) will run LSR on a Milacron-Fanuc Roboshot 140. The retrofittable LSR package includes a special Milacron screw and barrel with water jackets, vacuum pump, and water regulator.
Negri Bossi (Booth W363) is operating a 180-m.t. press in its relatively new Canbio ST servo-hydraulic toggle line, molding a ping pong paddle from PBT, TPU and both foamed and solid LSR.
 
 
Nissei (Booth W923) will team up two presses to mold a magnifier. The thermoplastic casing is made in a new NEX-IV all-electric press (121 tons), and then a robot passes the part to a FNX-II hybrid (121 tons) to overmold the LSR lens.
CAE simulation software provider Sigma Plastic Services (Booth S30023) will demonstrate an unusual two-color LSR molding application and compare the actual results with its “Virtual Molding” prediction.
