Liquid Silicone Rubber Injection Molding 

Our facility is state-of-the-art and features lights-out capable, fully-automated liquid injection molding (LIM) cells with inline vision technology, value-added operations stations, and finely tuned quality systems – all of which ensure we deliver high-quality, high-volume LSR parts to our customers.

All our services can be requested for high-volume or low-volume production runs. We produce millions of custom-formed LSR parts annually, welcome the smallest orders and provide the same quality service for high and low-volume production. Customers benefit from the high-volume production of Elimold finished parts and a shortened supply chain’s time and cost advantages.

For high-volume, long-term projects requiring LSR components, you can rely on elimold. We provide solutions for all stages of production, from design and prototyping to production support. Our decades of combined experience, advanced process technology, and strong quality systems have elevated us to the industry’s top.
Our LSR’s dedicated capabilities in the US and China allow us to deliver many services more efficiently than any competitor, and we deliver these services to a higher quality standard.

LSR Injection Molding

Innovative technology meeting customer needs

Liquid Silicone Rubber (LSR) can be processed in a liquid injection molding (LIM) process. The liquid raw material is mixed from two separate components in a ratio of 1:1 and injected via a cold-runner system into a hot mold. Curing takes place within seconds, offering the advantage of fast cycling and the production of large quantities.

Due to the flexibility in design and tooling, LSR injection molding is ideal for producing complex geometries and can consolidate various functional features into a single part. It also offers significant advantages in terms of product reliability and total cost of ownership.

Advantages of LSR molded parts

Limitless design – Enables production of part geometries and technical solutions impossible otherwise.

Consistent – Provides the highest consistency in the product dimension, precision, and overall quality

Pure – Silicone is one of the most extensively tested biomaterials with a long history of safe use

Precise – Flashless, wasteless tool design concepts for parts weighing from 0.002 grams to several hundred grams

Reliable – Using the latest technology in machinery, tooling, and automation

Quality – Zero-defect quality level through in-process controls

Fast – Enables highest volume production due to short cycle times, from several thousand to millions

Clean – Utilizing state-of-the-art processing techniques and production in Class 7 and 8 cleanrooms

Cost-effective – Offers the lowest Total Cost of Ownership (TCO)

LSR Parts Production

Elimold offers a wide range of options for LSR part production. We carefully evaluate each project to determine the best LSR injection molding technology for producing components: LSR, LSR two-shot, LSR multiple-shot, or LSR overmolding.
We have state-of-the-art facilities, and our production areas are clean with minimal human contact as our LSR, LSR 2k, multi-shot, and overmolding manufacturing cells are fully automated.
Many medical products have stringent cleanliness requirements that require specific ISO-certified hygienic production requirements. To meet these requirements, elimold is equipped with single and secondary LSR lines.

Only one LSR material is used for injection molding parts in this moulding process.

LSR is combined with two or more polymers or a polymer and substrate in this process for more complex components.

In overmolding, the liquid silicone rubber is molded around a substrate or finished component.

This injection molding process produces tiny, complex parts with a shot weight of less than 1 gram.

LSR parts are produced in a clean, hygienic environment that are highly-controlled to various levels, such as white rooms or more stringent ISO cleanrooms with various classifications.

We make millions of custom molded LSR parts per year.

With our production capabilities, we can produce high-volume products faster than our competitors, such as silicone-to-metal bonded, overmolded, and LSR custom molding services. Not only can we produce results quickly, but we can do so 24 hours a day, 365 days a year.

Because we are a trusted and respected Asian company, we can maximize productivity and pass on cost savings to our customers.

All LSR products produced by elimold are safe and manufactured in a dedicated, clean environment. We regularly supply companies with the most stringent cleanliness requirements in the industry. Our parts are frequently used in medical applications where the cleanliness and safety of parts are critical. That’s why we have dedicated production areas for all LSR products and strive to produce only the cleanest and safest products. By doing this, we have all LSR technologies under one roof. This passes the savings on to our customers.
