Custom Rubber Molding Services at TEAM MFG

As a leading manufacturer, TEAM MFG offers several rubber molding services to make you rapid prototypes, and low to high-volume production parts. Rubber injection molding, compression molding,  vacuum casting, and LSR molding are the core methods at TEAM MFG for rubber parts manufacturing. Here, we have a brief introduces of all these services:

Rubber Injection Molding Service

Our rubber injection molding process utilizes a state-of-the-art hopper and heated barrel system. This method efficiently feeds uncured rubber, then pushes it through a plunger into a heated chamber, ensuring precise mold filling. Our process is designed to support a wide range of durometers and custom shapes, with an emphasis on reducing flash and ensuring quicker cycle times.
 
  • High-Volume and Low-Volume Capabilities: We are equipped to handle both high and low-volume production, adapting our techniques to suit your needs.
  • Sophisticated Parting Lines: Our expertise in setting parting lines minimizes flashes on rubber molded parts, ensuring a high-quality finish.
  • Temperature Management: We rigorously control the injection molding temperature to balance flow, quality, and strength of the final product.

Rubber Compression Molding

Rubber Compression Molding Service

Recognized as one of the most cost-effective and widely used methods, compression molding is ideal for low to medium production volumes. This process involves pre-heating the polyurethane mold rubber material and compressing it into the mold cavity using a high-pressure press. It's particularly advantageous for producing large, bulky products like gaskets, seals, and o-rings.
 
  • Mold Construction: We design a two-plated mold, adaptable for closed and open structures.
  • Material Placement: The molding material, mixed with a curing agent, is placed in the heated cavity.
  • Mold Compression: The material is compressed, ensuring full contact with all mold areas.
  • Heating and Curing: The mold is heated to cure the rubber effectively.
  • Final Processing: After molding, we remove overflows and prepare the product for delivery.
     

Rubber Vacuum Casting Service

Vacuum casting is a manufacturing process used to produce rapid prototypes and low-volume plastic and rubbber parts. The process is often appreciated for its combination of speed, quality, and affordability in prototyping and short runs—especially compared to the long lead times of injection molding molds and liquid silicone rubber molding molds, silicone rubber mold is quick!
 
Common Applications
  • Prototypes that closely mimic injection-molded parts
  • Market testing units
  • Functional testing parts
  • Bridge production before mass production tooling is ready
  • Low-volume production for specialized devices or custom products
     
Vacuum Casting Rubber
LIM

Liquid Silicone Rubber(LSR) Molding Services

Liquid silicone rubber(LSR) molding is thermoset injection molding process that inject the liquid silicone into the mold cavity to mold the desired parts. 
 
 Material form: Mixing a two-part liquid (Part A + Part B)  together and cures (vulcanizes) inside a heated mold.
 Process: Usually molded by Liquid Injection Molding (LIM), which is fast, precise, and suitable for high-volume production. TEAM MFG also offers low-volume LIM solutions.
 Mold: LSR mold is a bit different with traditional plastic injection mold.
 Properties of molding silicone rubber
  • Excellent flexibility and elasticity
  • High temperature resistance (up to ~200°C or higher)
  • Cold resistance (down to -50°C)
  • Biocompatible (safe for medical and food contact applications)
  • Good electrical insulation
  • UV and aging resistance

Post-Curing and Stabilization

After the initial molding process, many rubber parts undergo a post-curing stage to enhance their physical and chemical properties. Post-curing is a controlled heating process that completes the vulcanization reaction, removes residual volatiles, and stabilizes the material for long-term performance. At TEAM MFG, we use precise post-curing methods to ensure every molded rubber part meets the required strength, durability, and stability standards.
Post-Curing and Stabilization

Why Post-Curing Matters

Post-curing plays a vital role in improving the performance of molded rubber components. It helps to:

 Increase heat and chemical resistance by completing crosslinking reactions.

 Enhance mechanical strength and elasticity, reducing deformation under stress.
 Improve dimensional stability for applications requiring tight tolerances.

Eliminate residual by-products or volatiles that could affect part performance or odor.

Our Post-Curing Process

TEAM MFG operates temperature-controlled ovens specifically designed for rubber post-curing.
  • Each batch is processed at the optimal temperature and duration based on the rubber compound type, such as silicone, EPDM, nitrile, or fluorocarbon.
  • This ensures uniform curing, improved hardness consistency, and stable material properties across all parts.
  • For high-performance applications, we also provide secondary stabilization to relieve internal stresses and prepare parts for critical environments like automotive, aerospace, and industrial sealing.
