RUBBER & PLASTIC MOLDING
Injection Plastic Molding
Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. It’s done most commonly using thermoplastic and thermosetting polymers. Injection molding is widely used for manufacturing a variety of industries, from the smallest components to an automotive body panel.
Our injection molder is an overseas supplier and can handle any size at unlimited volumes.
Injection Rubber Molding
Rubber injection molding generally consists of rubber strips fed into a chamber for preheating. The melted rubber is then forced into an injection tool with hydraulic pressure. The rubber travels through a runner system, through the feeders into the cavity that forms the part configuration. This is different from the plastic injection molding process where the materials are cooled under less pressure.
Advantages of rubber injection molding:
- Reduced cycle time
- Flash-less tooling
- Economical process for high volumes of medium-to-high precision components
- Minimal material waste
Transfer Rubber Molding
Transfer molding is similar to injection molding in that it uses pressure to force rubber through feeders and then into the cavity that forms the rubber part configuration. The main difference is with the use of a pot and force, or use of a transfer press, a pot and ram. A main benefit to this operation is allowing the tool to completely close prior to rubber being fed into cavity. This allows for minimal flash, quick color change over, and aids in feeding difficult or complex part geometries.
Compression Rubber Molding
Compression rubber molds are generally the least expensive of the three types of tooling that are typically used in the rubber industry. Part configuration, material, and estimated run quantities are some of the considerations used to decide the best tooling approach. Compression type tools are often the preferred choice when budget and production quantities are limited.
Compression molding is often chosen for medium hardness compounds in low volume production or in applications requiring particularly expensive materials. This process helps to minimize the amount of overflow, or flash created during the rubber molding process.
A power cord, line cord, or mains cable is an electrical cable that connects an appliance to the main electricity supply via a wall socket or extension cord. Our power cord manufacturer can custom design and manufacture electrical power cords, extension cords, wire harness, international power cords, and detachable cord sets for every industry. They are all made in the USA and UL approved.
