Rubber Molding Methods Offer Essential Functionality

The use of rubber has revolutionized much of the world. In fact, without rubber, many of the daily conveniences that most people take for granted would not even be possible, or if possible, they would not operate in the same way. Rubber cushions, isolates, eliminates unwanted vibration, noise, and even offers better traction for moving parts. Rubber is used for an incredibly diverse number of applications. However, there is one key to all of these diverse uses – rubber molding techniques.

Rubber molding is a science unto itself, with a number of different techniques and technologies involved. Through the process of specialized molding techniques, any type of rubber design can be created, from air inlet elbows to locomotive boots, voting machine parts, silicone rings for heart and lung machines, viton seals and much, much more. What sorts of molding techniques are used in the industry, and what does each technique have to offer? Here is a glimpse of the technology behind the functionality that most of us take for granted.

Compression Rubber Molding: This method uses a compression mold to create rubber parts and forms. In essence, this process simply requires that a mold be opened, an uncured slug of rubber be inserted and then sufficient compression be placed on the now-closed mold to shape the rubber into the desired shape. Molds can have a single cavity and two plates, or they can be configured in numerous different ways to create the desired form.

Transfer Rubber Molding: Transfer molding is quite a bit like compression molding, in that it uses a mold to create the final form. However, material is transferred from the “pot” by the force of a plunger and enters channels, or “sprue,” and runners to fill the cavities within the mold. This is used to create a wide range of different parts, particularly those where a need for delicate rubber pieces or high-definition pieces is required.

Injection Rubber Molding: Injection molding is used with numerous different materials, including rubber and plastics. It results in pliable parts that are also durable, and is capable of high-speed mass production. Rubber is injected into a mold and the amount is metered to ensure the correct amount is used. This material is injected into a mold, which is secured with a clamp. An incredible diversity of products can be manufactured through the process of injection molding.

The key to having the high-quality rubber components that you need is to choose a company with the utmost experience and expertise in rubber molding techniques. The best option is to choose a firm that offers all three of the abovementioned techniques, as this will ensure that you can have any type of rubber component manufactured that you might require, from delicate rubber items to highly detailed, complex rubber boots. Of course, you should also make sure that the company has experience making similar products, as this will certainly play a role in your satisfaction with your finished rubber pieces.
