Compounding

At Standard Rubber Products, the compounding process begins with the precise weighing and batching of raw materials, including the EPDM base polymer and various additives. The first step is to prepare the carbon black master batch, which is then aged to ensure better dispersion.

Once the master batch is ready, it is mixed with the base polymer using a mixing mill. This machine provides efficient and thorough mixing, ensuring a uniform distribution of carbon black and other additives throughout the EPDM compound.

During the mixing process, various additives are incorporated to enhance the performance of the final rubber compound. These additives may include curing agents, accelerators, processing aids, and other compounds based on the desired properties of the end product.

Throughout the compounding process, quality checks and tests are performed to ensure that the compound meets the required specifications and standards. This ensures the consistency and high quality of the EPDM compound.

Once the compounding process is complete, the final EPDM compound is ready to be used for extrusion or moulding. This compound is fed into the extrusion machine, where it is shaped and formed into the desired rubber profiles used in various applications across industries.

Extrusion

After the compounding process, the next step is extrusion, where the compounded rubber is shaped and formed into rubber profiles, including rubber beadings.

The process of UHF extrusion (Ultra High-Frequency extrusion) involves the following steps:

UHF extrusion offers advantages like reduced production time, improved energy efficiency, and precise control over the curing process. This makes it an ideal choice for producing high-quality rubber beadings and other rubber profiles efficiently and effectively.

Moulding

After the compounding process is complete, the rubber compound is ready to be used for the manufacturing of moulded rubber parts at Standard Rubber Products. Here's an overview of the process for moulded parts:

Mould Design and Preparation: The first step in the moulding process is the design and preparation of the mould. The design is based on the specific shape and dimensions required for the moulded rubber part. The mould is typically made from metal and consists of two halves that fit together.

Mould Preheating: Before the rubber compound is placed in the mould, it is preheated to a specific temperature to improve flow and ensure better mould filling.

Injection or Compression Molding: There are two common methods for molding rubber parts: injection molding and compression moulding.

Injection Moulding: In injection moulding, the preheated rubber compound is injected into the mould cavity under high pressure using an injection moulding machine. The rubber fills the mould cavity, taking the shape of the mould, and is allowed to cure.

Compression Moulding: In compression moulding, the preheated rubber compound is placed directly into the mould cavity, and the mould is then closed. Pressure is applied to the mould to compress the rubber and shape it according to the mould design. The rubber is cured in the closed mould.

Curing: After the rubber compound is moulded into the desired shape, it undergoes a curing process to achieve its final physical properties. The curing process involves applying heat to the moulded rubber part for a specific time to promote cross-linking of the polymer chains, resulting in improved strength and durability.

Cooling and Demoulding: Once the curing process is complete, the mould is opened, and the cured rubber part is removed. The part is allowed to cool to room temperature before further processing or quality inspection.

Trimming and Finishing: After demoulding, the moulded rubber part may require trimming or finishing to remove any excess rubber or imperfections, ensuring the part meets the required specifications and tolerances.

Quality Inspection: Every moulded rubber part undergoes thorough quality inspection to check for dimensional accuracy, physical properties, and visual defects. Standard Rubber Products maintains strict quality control measures to ensure that each part meets the highest quality standards.

Packaging and Shipping: After passing the quality inspection, the moulded rubber parts are carefully packaged for shipment to customers or further assembly into final products.
