Have you ever been curious about how raw rubber is transformed into a wide range of shapes and forms, from the grip of your pen to your car’s tires?
The whole transformation of raw rubber to its products happens through rubber moulding. However, this process is a little more complex than it is. It involves various unique techniques to deliver the end product.
Rubber plays a significant role in keeping our daily lives complete and connected. From the sole of our shoes to the tires of our cars, rubber is used in everything. Rubber products are not only excellent in terms of their thermal and insulating properties, but they are also versatile, flexible, and long lasting, making them ideal for demanding industrial applications.
As one of the prominent rubber moulded products manufacturers in India, GB Rubber is recognized for delivering top-of-the-line rubber products with various features, materials, and dimensions to meet diverse industrial needs.
Further, let us delve into the fundamentals and various types and aspects of moulding being employed across the rubber industry.
What is Moulding?
In simple terms, moulding is the process of shaping a material into a desired form by pouring a molten or semi-liquid material into a mould and allowing it to harden or solidify. Once the material has been moulded, it is cooled and removed from the mould.
The mould is usually made of metal or plastic and is designed to give the object a particular shape and size. The process is commonly used in producing plastics, ceramics, and metals and has been widely adopted across different industries worldwide.
What is Rubber moulding?
Rubber moulding is a highly effective manufacturing process that involves the transformation of liquid rubber into a desired form using a mould. This process begins with heating the rubber material until it melts, then injecting it into a mould. Afterward, the mould is cooled, and the rubber solidifies, taking the shape of the mould.
With the increased level of industrialization, this manufacturing process has become one of the most essential ones in the world. Although rubber products have numerous benefits, the primary advantage of this process is that it is cost-effective and allows for the production of rubber products in large quantities with high precision. In addition, this process is also ideal for creating high-quality, complex rubber products with tight tolerances and intricate designs.
We, at GB Rubber products also utilize the moulding process to produce the highest quality rubber products and impressive customer service.
The Types of Rubber Moulding Methods
1.Rubber Injection Moulding
Rubber Injection Moulding is a type of rubber moulding process wherein rubber material is heated to a molten state and then injected into a pre-designed mold cavity under high pressure. The mold is then cooled to allow the rubber material to solidify and take on the desired shape. This process enables manufacturers to create intricate and complex shapes, as well as products with consistent quality and performance.
The versatility of the rubber injection moulding process is noteworthy as it can be utilized with a variety of rubber materials, such as EPDM, neoprene, nitrile, and silicone. This makes it an ideal manufacturing technique for creating a diverse range of molded rubber products, including gaskets, seals, o-rings, and various automotive parts.
Compression moulding, one of the earliest moulding processes, shapes rubber by applying heat and pressure using a mold tool and clamping press. The curing process occurs before removing the final product and allowing it to cool.
Compression moulding is most suitable for parts with a large cross-sectional area and has a greater capacity to process stiff, high-durometer materials. This process has various advantages, for example, low levels of wastage, simpler tooling, and is more cost-effective when compared to injection moulding.
When looking to buy rubber products for your industry applications, look for top rubber compound manufacturers in India that offer reliable, long-lasting, and top-quality solutions. Ensure choosing the one that fulfills your specific industry requirements.
In transfer moulding, the raw materials are first prepared as pre-forms and then inserted into a pot located within the mould tool. Subsequently, the mould is pushed through a runner and gate system and is vulcanized with the application of heat and pressure. The rubber is injected into the cavity after securing the mould, much like injection moulding.
Transfer rubber moulding has various advantages over compression moulding, such as improved accuracy and consistency and a shorter manufacturing phase due to the ability to use multiple cavities.
As we talk about rubber moulding, let’s discuss about rubber metal bonding as well.
Rubber metal bonding takes place when rubber and metal are combined to create a strong, durable, and flexible material. This type of bonding is commonly used in industrial applications where there is a need for shock absorption, vibration damping, and noise reduction.
Rubber metal bonded parts are often found in the automotive, aerospace, and construction industries. The bonding process can be achieved through a variety of methods, including injection moulding, compression moulding, and over-moulding. The resulting material offers a range of benefits, including improved performance, longer lifespan, and increased safety.
