LSR Injection molding mold Making
With a wealth of experience and state-of-the-art machinery, we specialize in designing and manufacturing a wide range of liquid silicone rubber injection molding molds that meet your tolerances and cost requirements.
liquid silicone injection molding parts for medical
Our liquid silicone rubber injection molding process uses precision machinery to inject liquid silicone rubber into molds, resulting in medical-grade parts.
Liquid silicone over molding metal parts
By chemically bonding plastics, metals, and rubbers to each other, our overmolding reduces assembly time and gives our parts greater strength and flexibility.
Liquid silicone over molding plastic parts
Soft, liquid silicone rubber is injection molded along with hard plastics to create finished parts that incorporate multiple materials.
Ordinary liquid silicone injection molding
Liquid silicone rubber injection molds can be molded for more types of products in addition to the above, contact us for detailed support.
Quality Inspections
Quality, safety and customer satisfaction are core values of our injection molding services. Where appropriate, we perform 100% inspection. In other cases, we work with you, our customer, to establish AQL standards. Our return rate is less than 0.01%, which speaks to our attention to detail. We produce all molds in-house to ensure superior quality and intellectual property protection. This also reduces lead time, so we can get your custom injection molded product started and to market faster. We handle large and small batches with the same professionalism and efficiency, and we will always complete the work within your tight schedule.

How Does Liquid Silicone Rubber Molding Work?
First, the formula of the liquid silicone rubber mixture is divided into two parts and conveyed from the barrel to the static mixer in a certain proportion. In addition, if you have more requirements for the product, you can allow the raw materials to add colorants or other additives to change the hardness before mixing.
In the static mixer, the compound is fully mixed, even better than pre-mixed solid silicone rubber. After that, the LSR compound is pushed into the metering part of the injection unit, and the cooling system will work so that the LSR compound will not undergo unnecessary catalytic reactions, thereby effectively reducing the possibility of material waste.
Then, the LSR compound enters the mold cavity and solidifies under the action of high temperature and high pressure. This process is very fast and usually lasts only a few seconds. After completion, the product is removed from the mold, re-injected with liquid silicone rubber, and the next production cycle begins. This is the process flow of silicone rubber injection molding.
Benefits
LSR injection molding offers custom manufacturing opportunities and is a popular solution due to its ability to mold complex part geometries, excellent mechanical properties, and purity. Other benefits include:
- High tear strength
- Excellent optical clarity for maximum light transmission
- UV resistance
- Biocompatibility
- Low compression set
- Excellent chemical resistance
- Withstands harsh environments from cryogenic to elevated temperatures
- Ability to overmold and bond to a variety of substrates such as plastics and metals
- Customizable additives such as antimicrobial, conductive, self-lubricating, and antistatic agents
