Rubber Injection Molding

Founded in 1978, Zhongde is a professional silicone mold company focusing on OEM & ODM customized services. Based on 40 years technology deposition, we have developed a one-stop solution from mold designing and rapid prototyping to mass production. Our manufacturing capabilities include plastic injection molding service, compression molding service, CNC machining service, metal stamping service, 3D printing service, custom molding service,etc.  

Rubber injection molding can be used to produce both solid rubber parts and rubber bonding metal parts, it is an ideal process for mid-to-high volume rubber production. This is a process that fully automated and becomes one of the most efficient ways to mold rubber in most cases.

At Zhongde, we are determined to provide customers with superior products that meet high standards. As a longtime supplier for top-quality custom rubber parts, we are well-equipped to undertake a wide range of rubber materials, uphold precision tolerances within ±0.5mm.And now the silicone injection molding cost is pretty appropriate.

Additives of Rubber Injection Molding

Name Description
UV absorbers Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants Prevent ignition and inhibits spread of fire.
Colorants Used to color rubber
Vulcanizing agent Converts polymers and rubber into a more durable, rubber-elastic material end product
Tackifiers Give a short and long-term tack, casing two layers to bon together with light pressure.
Plasticizers Improve the flow of rubber during processing
