Plastics Shrinkage Rate & Mold Shrinkage Rate

 Plastics Shrinkage Rate & Mold Shrinkage Rate

It is very important for each product design to know the plastics shrinkage rate. So that when he designs his parts design, he can present the right scale size of the drawing to mold  manufacturing factory like Intertech.

Meanwhile, the mold shrinkaged rate provides good information for production injection molding factory for calculating the final finished product size to be stablized in final shape.

As molding processes gain grounds in the manufacturing sector, injection materials such as liquid silicone rubber are witnessing a sharp increase in terms of demand. Versatile characteristics and unique properties of liquid silicone rubber is driving its value in the elastomer industry, wherein a wide spectrum of consumer products, medical devices and industrial goods are being manufactured by injecting liquid silicone rubber into mold cavities. Future Market Insights estimates that by the end of 2026, the global market for liquid silicone rubber will touch a valuation of US$ 7.9 billion.

The study foresees a moderate growth for the expansion of global liquid silicone rubber market during the period, 2017-2026. It has been estimated that the global liquid silicone rubber market will register a value CAGR of 4.5% over the forecast period. High carbon footprint of producing liquid silicone rubber at large scale, limitations to the reuse and recyclability of such elastomers and disposability challenges are set to deter the use of liquid silicone rubbers in the near future.

Molding capabilities of liquid silicone rubbers will drive their use across several industrial applications. It has been observed that industrial grade liquid silicone rubber will showcase robust growth in demand in the coming years. Through 2026, nearly half of the global liquid silicone rubber market value will be accounted by sales of industrial grade elastomers. The report also foresees that liquid injection molding technology will be a sought-after in the global liquid silicone rubber market. In 2017, more than US$ 3.2 billion worth of liquid silicone rubbers will be used by liquid injection molding systems across the globe.

The study has identified key industries that will drive the end-use of liquid silicone rubber in the near future. Consumer goods industry will reflect highest profitability in the end-use of liquid silicone rubber for manufacturing fast-selling products such as buttons and rubber gaskets. By the end of 2026, US$ 1.76 billion worth of liquid silicone rubber will be used in the production of consumer goods worldwide. Furthermore, healthcare landscape will also exhibit fast-growing end-use of liquid silicone rubber over the forecast period. Liquid silicone rubber manufacturers will find lucrative profit margins will selling these elastomers in the production of expensive medical devices such as lung catheters. The report also observes the automotive industry as a lucrative end-user of liquid silicone rubbers. Over the forecast period, automotive end-use of liquid silicone rubber will reflect highest value CAGR of 5.4% in the global market.

China National Chemical Corporation, Shin-Etsu Chemical Co., Ltd., KCC Corporation, Toshiba Medical Systems Corporation, and Zhejiang Xinan Chemical Industrial Group Co., Ltd. are among the prominent manufacturers of liquid silicon rubber based in Japan, China, Korea and other parts of the Asia-Pacific region. The report estimates that in 2018 and beyond, the Asia-Pacific excluding Japan (APEJ) region will represent largest marketplace for liquid silicone rubber, reflecting a weighted 35% share on global market value. Other key players in the global liquid silicone rubber market, namely Dow Corning Corporation, Momentive Performance Materials, Inc., Evonik Industries AG, Bluestar Silicones International, SiVance, LLC, NuSil Technology LLC, Simtec Silicone Parts, LLC, Wacker Chemie AG, Stockwell Elastomerics Inc., and Xinapse Systems Ltd. are also expected to bolster their presence across the APEJ region in the foreseeable future.

Choosing the right color for your silicone product

Choosing the right color for your silicone product

The color of your silicone product can attract your consumers and increase big sales amount in

your business.  And for choosing the right color for your silicone product, you defenitely need

an experienced mold maker and molding factory like Intertech to help you to reach this goal.

http://www.taiwanmoldmaker.com/product/silicone-product

We help you to do the silicone color matching issue :

Though the color pigment for silicone is available everywhere, but the key to success is in the

pigment percentage of mixing with the silicone material.  Different durometer of silicone

rubber, different percentage of pigment mixing.  We usually use silicone rubber material in the

40-70 shore A, compounding with different percentage of color pigment, up to each customized

requirement.  To make the same and stable color silicone product performance in each lot of

production lot is never an easy thing, ..the climate, temperature, perceptional judgment and the

production experience are all relatively important !  Intertech is one of the few color experts

in running silicone product projects !

In terms of color on silicone material choosing, Intertech helps you :

Pantone Color Match:

Pantone numbers is the international standard code for colors.  Customer needs only to

choose the required code from Pantone, Intertech will then help customer to mix the suitable

pigment to certain specified grade of silicone material to match such pantone color, and test out

the new colorful silicone product samples again and again till getting the customer’s approval.

Physical Color Match:

Customer can also provide any kind of physical items to be as color match media. As per

Intertech’s experience, we can match the right silicone product color by presenting the

satisfied trial out samples.

  

FDA Compliance

Both the silicone material and the color pigment material that Intertech uses will fit for FDA

compliant.  It will be safe for contact with food and skin or medical application purpose.

Intertech has rich mold making and molding experience with any food safe, skin touch safe and

medical touch safe FDA compliant products project.

Again, to make the same and stable color silicone product performance in each lot of

production lot is never an easy thing in handling your assignment, Intertech, no doubt,

is your reliable partner for solving the color issue in your silicone product’s development !
