Rubber Mold Design
What is Rubber Molding?
Rubber molding is a process to convert unprotected rubber or elastomer into a useful product by transferring, compressing or injecting raw rubber material into a metal mold cavity. The applied pressure creates a chemical reaction, such as curing or vulcanization, that causes the polymer chains in the material to crosslink.
All rubber manufacturers use heat and pressure to produce their products. The most common methods for rubber molding are injection, compression, and transfer. With the continuous development of products, rubber mold manufacturers are constantly adjusting to meet the growing demand for grommets, gaskets, tubing, O-rings and hoses.
Use of rubber molding:-
Rubber, synthetic or natural, can be shaped and molded into complex forms, shapes and configurations, greatly increasing its usefulness. The flexibility and durability of rubber gives engineers many ways to design seal and cushioning components. The stability of rubber is seen in its use as a method of cushioning machinery to reduce impact and vibration.
While natural rubber is still widely used, manufacturers have developed synthetic versions of rubber that have the same strength as natural rubber with greater durability and longevity. Man-made materials such as neoprene, silicone, ethylene propylene diene monomer (EPDM), and a variety of elastomers have properties similar to rubber but have greater ductility and endurance.
Rubber bumpers come in a variety of shapes and sizes that are used in the manufacture of specific products such as recessed, mushroom, stem, grommet and tackle bumpers. Bumpers reduce vibration and movement in equipment to protect hardened parts from vibration and impact damage. They protect furniture, work surfaces, circuit boards, displays and packaging.
Rubber bushings are somewhat like rubber bumpers because they are designed to absorb vibration and impact on machinery.
Rubber grommets are rings that are placed around a metal opening to protect objects or materials passing through the opening. A common use for grommets is for openings through which wires pass.
Rubber Suction Cups
Rubber suction or vacuum cups are used as a handling system for manipulating objects with a flat surface such as glass, sheets of metal, wood paneling, molded pieces or tubes. They come in many shapes, sizes, diameters and types of rubber materials.
Rubber washers are a flat disc with a hole in the middle that are used as a load, spacer, wear pad, a method of locking a seal, or a way to reduce vibration. The dimensions of rubber washers are determined by their outer diameter (OD) and inner diameter (ID), which vary according to the washer’s use.
