Custom Rubber Injection Molding Service
Jiangzhi offers custom rubber injection molding for both low-volume and end-use production. Typically, we use steel as the tooling material to ensure mold durability. Our mold costs start at only $500. Additionally, we provide a variety of elastomers, allowing you to choose the perfect material for your rubber injection moulding process project.
What Is Rubber Injection Molding ?
Rubber injection molding is an advanced manufacturing process for producing high-precision, durable rubber parts. Using custom molds, we inject silicone or thermoplastic elastomers (TPE) into molds under high pressure, ensuring consistent quality and complex designs. This process is ideal for high-volume production, providing cost-effective solutions with excellent elasticity, durability, and customization. Whether for automotive seals, medical devices, or consumer goods, our rubber injection molding services offer reliable and efficient solutions to meet your specific needs.

FAQs of Rubber Injection Molding
How Can Jiangzhi Help Me with Custom Rubber Injection Molding Solutions?
At Jiangzhi Rubber, we specialize in creating custom solutions to meet your specific needs. From helping you select the right materials to designing and optimizing molds, our experts will collaborate with you to ensure your parts meet the highest standards of quality, performance, and cost-effectiveness. Whether you’re looking for a small prototype or large-scale production, we’re here to bring your vision to life.
How is Rubber Injection Molding Different from Traditional Plastic Injection Molding?
Great question! The main difference is the temperature and pressure requirements. Rubber molding often needs higher temperatures and pressures to melt and mold the rubber. Plus, there’s usually a curing (vulcanization) process that gives rubber its unique elasticity and durability, unlike plastics.
How Do You Choose the Right Rubber Material for Injection Molding?
Choosing the right material depends on what you need the final part to do! Consider factors like flexibility, heat resistance, chemical exposure, and budget. Your material choice will ultimately impact the part’s performance in its intended application.
What Are Common Issues in Rubber Injection Molding and How Do You Fix Them?
Common Problems: Air bubbles, surface imperfections, mold blockages.
Solutions: Adjusting process parameters, tweaking material formulations, and conducting regular mold cleanings can help keep things running smoothly.

Rubber Compression Molding
In compression molding, a pre-measured amount of rubber is placed directly into a mold cavity. The mold is then closed, and heat is applied. This process uses pressure to push the rubber into every crevice of the mold. The result is a solidified rubber part that matches the mold’s design exactly.
