Our Liquid Silicone Rubber Injection Molding Capabilities For The Medical Industry

Since Liquid Silicone Rubber Injection Molding can produce intricate elastomeric components in short cycles, it is steadily gaining a foothold in the medical markets. At Anpllocnc, a rubber & silicone molding company, we depend on this material due to its biological inertness and long-term product stability.

Liquid Silicone & Rubber Overmolding

For reducing costs, improving the quality of our medical products, and extending their lifetime performance, we utilize liquid silicone and rubber medical overmolding techniques. Due to its biocompatibility, we use silicone overmolding to produce a broad array of medical devices.

Silicone Micro Molding

We use silicone micro moulding, the latest trend in LSR manufacturing to produce small, highly accurate, and high precision parts. As the medical components are getting smaller, we strive to deliver our customers incredible accuracy and precision in all our LSR products.

LSR Compression Molding

Our team of experts utilizes this highly complex molding technique for producing composite medical components assembly in high production volume. LSR compression molding procedure involves low tooling costs. This is best for manufacturing large items and thicker parts, and is cost-effective for short production runs.

Silicone Prototype

For the medical industry, we also manufacture silicone prototypes by employing a lot of patience and experience. We understand that moving ahead without a prototype is extremely difficult. That is why we offer silicone prototypes to verify that your design will perform as intended.

Silicone Insert Molding

At Anpllocnc, we use the silicone insert moulding products and techniques for the medical industry as it molds the silicone through a substrate material to produce the final part. By combining the best of two materials, this process supports variations in durometer and rigidity.

LSR Tooling

Creating a precise, high-quality liquid silicone rubber part must begin with a high-quality mold. At Anpllocnc, we have in-house CNC milling and CNC electrical-discharge machining tools that allow us to create your mold with incredible precision and meet even the tightest requirements for tolerances.
Developing your LSR mold is usually the most expensive part of developing a liquid silicone rubber part. It takes expertise and patience to create an aluminum tool mold that will hold up to the high temperatures of the LSR molding process and provides you with a molded product that meets your specifications.
However, there are some things that make the production of an LSR mold easier, compared to a traditional injection mold. First, there is no need for a highly polished finish for liquid silicone rubber products. Also, since the material readily deforms and resumes its original shape, there is no need to worry about proper draft angles for ejecting the solidified product.

With LSR presenting many challenges in the molding process, a high degree of precision is expected and required for every mold we build. Our molds deliver a high level of efficiency and productivity, while providing excellent value throughout the life of the tool. We’re one of the few companies in the china offering waste-free LSR molds utilizing our own proprietary cold runner system. Tools are built to imperial and metric standards.

Our highly skilled staff excels in translating complex 3D part geometry into state-of-the-art injection molds. Our customers are comfortable knowing they’re working with a high level mold builder whose expertise goes far beyond simple flat parting line tools. Although we specialize in liquid silicone molds for medical applications, Anpllocnc serves many other industries, including dental, aerospace, automotive, and consumer products.

Silicone Injection Molding manufacturing process

Liquid Injection Molding

Liquid Injection Molding (LIM), also referred to as Liquid Silicone Rubber (LSR) molding, is an injection molding process that uses a high viscosity liquid in two parts that is mixed with a platinum catalyst to enable a much faster cure rate compared to the injection molding of high consistency (HCR) rubber. The faster cure rate makes it ideally suited for high-volume manufacturing. LIM/LSR molding is a closed system of molding, so the uncured raw material never comes into human contact. This molding process is ideal for high purity applications such as in the medical, biopharmaceutical, food processing, dairy, and semiconductor industries.

The liquid injection molding/liquid silicone rubber molding process is ideal to produce complex designed parts such as three-dimensional configurations, parts with multiple thicknesses, undercuts, and high-volume overmolding. At Anpllocnc, we have taken the manufacturing process of LIM/LSR molding to a new level through our engineered quality system. This system provides our customers with a level of quality that is engineered into the process from the beginning of your project. Anpllocnc welcomes low-volume prototype and development quantities to high volume production while producing high purity, precision tolerance parts for a wide range of applications.

Features & Benefits of LSR Injection Molding

Liquid Silicone Rubber (LSR) is a versatile material that is flexible, cheap, and can resist chemical reactions. Hence, making it ideal for machine parts, household appliances, medical equipment, etc. Injection molding is a high-tech process that has revolutionized the rubber manufacturing process and enabled us to produce far more complex designs in larger quantities than were previously impossible.

High Production Volume

We can handle LSR components of all volumes, and create cost-effective, automated solutions to meet your needs.

Low Risk Of Contamination

Since the part fabrication process occurs in a “closed system” there is a very low risk of the operator or environment contaminating your part.

Easy To Automate

LSR part production with injection molding is very easy to automate compared to other methods of creating liquid silicone rubber parts.

Produces Less Waste

LSR injection molding does not produce scrap “flash,” because it can be used with flashless molds. This helps reduce waste and cost.Beyond this, liquid silicone rubber itself has some beneficial characteristics which may make it a good choice for your product.

Safe And Food/Medical Grade

LSR can be used to manufacture food-grade and medical-grade components, since it’s clean, inorganic, tasteless and resists bacterial growth.

Biocompatible

Liquid silicone rubber is compatible with human tissue and bodily fluids.

Electrical Insulation

LSR is an excellent electrical insulator, even compared to HCR and solid silicone.

Transparent

LSR is completely colorless and transparent, which opens up a lot of unique possibilities. It can also be pigmented during the injection process.

Chemical Resistant

Liquid silicone rubber resists common acids and alkali, water, oxidation, and some organic solvents.

Heat-Resistant

Liquid silicone rubber can withstand both high and cold temperatures without deformation or damage.
