Custom Rubber Molding – Processes And Advantages

Manufacturers utilise various rubber molding processes in order to design precision rubber components and rubber-to-metal bond assemblies. The process has many advantages for which it finds application in almost every industry, and also in products of residential applications. Injection molding is the most commonly used process that gives benefits like tight tolerance, high volume, precision, and so on. The process has a high level of automation as compared to other rubber manufacturing processes like rubber transfer or compression moulding. Injection moulding is an optimal method also for providing good control over flash, waste, and faster rubber cure times as compare to other methods in use for manufacturing Rubber Molding Products.

The use of rubber in various processes and as crucial components has revolutionised the world. If you think carefully, you would understand that many of the daily conveniences that you enjoy would not be there without rubber. Some of the commonly used components include rubber isolates and cushions that are used to avoid unwanted noise, vibrations from various sources. In fact, rubber products are also used to provide better traction for movi

ng parts. The credit for the diverse applications of rubber goes to different molding techniques, especially injection molding.

The injection molding process

The process of high speed mass production requires uncured rubber ribbon stock. The material is then fed into the rotating screw of the injection unit. You should remember that only a controlled amount of material is used in the step. The process takes place at an elevated temperature to plasticize the rubber. The material is later injected into a mould cavity by means of a runner and a gate system, and here it is held at a high pressure and temperature conditions. The condition is important to facilitate the cure system or to vulcanize the rubber. The cycle time is determined to ensure an optimal level of cure. Parts are manufactured at the end of the cycle and then ejected from the cavities to begin the next cycle.

Custom Rubber Molding Manufacturing ON companies use injection molding for the advantages it has to offer:

• Offers high level of repeatability

• Ensures automation of the process with automatic material feeding

• Good for high precision moulding applications

• Due to its closed mold injection, it is good for products that feature complex geometries and over-moulding

It has some downsides as well:

• Higher cost associated with start-up and shut down

• Good for mass production only

• Not every cure system or elastomer is good for the process
