Rubber forming molds produce rubber products, such as caps, seals and grips. A wide range of industries, including medical, automotive and aerospace, implement rubber mold making. Typically, rubber mold products are the result of pouring liquid rubber into the mold, which can be heated, cooled, expandable or have multiple parts.

Rubber mold forming processes include injection molding, transfer molding, blow molding, compression molding and cast molding. All molding techniques are similar in nature. Injection and blow molding force liquid rubber into the mold. Injection molding uses a cooled mold while blow molding utilizes expandable tubes. Compression molding melts slugs of rubber with heated molds. Transfer molding also uses heated molds with the mold split in half. When contracting rubber forming mold services, consider the following:

1. Order custom rubber molding for unique applications.

2. Use rubber mold manufacturers experienced in your industry.

3. Purchase silicone rubber mold products for durability and heat resistance.

Action Steps
The best contacts and resources to help you get it done

Order custom rubber molding

Unique applications require custom rubber forming molds. Place an order with a custom rubber mold manufacturer if standard products won't work for your application. Custom rubber mold manufacturers work with you during the design of your product to ensure the final result meets your specifications.

I recommend: Order custom rubber products from IMS. Purchase custom single-cavity and multi-cavity rubber forming molds at Estee Mold and Die. Custom rubber mold manufacturer Randolph Austin is capable of compression molding, transfer molding, rubber to metal bonding, prototypes, as well as research and development. Precision Associates is a custom rubber forming molds manufacturer that offers rubber injection molding and transfer molds.

Use rubber forming mold manufacturers that are experienced with your application

When ordering rubber forming mold products, make sure the manufacturer is familiar with your particular industry and application. Many times, an application requires specific natural and synthetic materials, and the product will deteriorate if the material can't tolerate extreme conditions. Using an experienced company offers you the confidence of knowing your product's materials are adequate.

I recommend: Order rubber molds for turbine vane and blade masks from Straton Industries. The company specializes in the repair of helicopter and fixed wing aircraft components. Paramount PDS employs tooling engineers and technical specialists who can suggest the correct injection molding materials for your application. Armstrong Mold routinely serves the telecommunications, automotive, aerospace, military and medical industries.

Purchase from silicone rubber mold manufacturers

Silicone rubber is a durable and heat-resistant material. The material is also free of leachable chemicals and allergens. Silicone rubber molds are produced from injection molding, compression molding, cast molding, dip molding or liquid injection molding.

I recommend: Order silicone rubber forming mold products from International Rubber Products. The company's molds are available through insert and injection molding. AMERIMOLD Tech is a custom manufacturer and designer of rubber and silicone injection molded products.
