Moulds

Mould is the heart of roto moulding process. Moulds can be in materials like MS, Stainless Steel etc. Mould making is an art since the quality of the mould decides the end product.

Molding  are used to create ceramic, rubber or elastomer, plastic, glass, composite, silicone, and metal parts by molding with liquid material, or pressing solid materials or powders into a die or form.

Processes employed in molding may include casting, compression molding, compaction, ramming, hot pressing, cold pressing, injection molding, resin injection molding, transfer molding, thermoplastic molding, thermoset molding, rubber or elastomer molding and other specialty molding technologies. A wide variety of parts can be fabricated using molding processes such as mechanical components, housings or cases, seals, gears, impellers, valve parts, belting, dielectrics and insulation, bumpers, vibration absorbers, nozzles and ferrules. Molded parts have applications for OEMs in the automotive, heavy-duty, industrial, energy, materials processing, chemical processing, defense, aerospace, appliance and the medical, industrial controls, medical devices, laboratory products, safety, consumer, telecommunications, electronics and electrical industries.
