  • Motorcycle Parts Injection Mould 03
    Motorcycle Parts Injection Mould

    Motorcycle parts injection moulds are mainly used to produce motorcycle shells, mudguards, lamp frames, instrument panels, fuel tank covers, and various decorative parts. These moulds require high impact resistance, dimensional stability, and surface finish. They typically use high-strength mould steel and precision machining processes to ensure the products have excellent durability and stability in outdoor and driving environments. Advantages High moulding precision: Suitable for motorcycle parts with complex structures and strict assembly requirements. Excellent surface quality: Achieves high-gloss, textured, and paint-grade surface effects. High durability: Long mould life, suitable for continuous high-volume production. High customizability: Cooling systems, hot runners, and automatic core-pulling structures can be customized according to customer vehicle models, part structures, and production volume requirements. Widely used by vehicle manufacturers and the aftermarket, including mass production of body panels, functional structural parts, and exterior decorative parts, meeting the plastic parts supply needs of different vehicle models and markets.

  • Home Appliance Injection Mould 02
    Home Appliance Injection Mould

    Kaiji specializes in the R&D and manufacturing of injection moulds for home appliances, covering air conditioner housings, TV back panels, refrigerator liners, air conditioner panels, washing machine drums, and various bathroom plastic parts. Based on the high requirements of the home appliance industry for surface quality, structural strength, and dimensional stability, we utilize high-quality mould steel, precision high-speed machining equipment, and optimized cooling systems to ensure that products are shrink-free, deformation-free, and have a high-gloss finish. Kaiji has extensive experience in large-scale mould manufacturing and can customize solutions such as reinforced structures, hot runner systems, and automated core-pulling based on customers' annual production needs, improving production efficiency and reducing maintenance costs. We provide a one-stop service from product structure optimization, mould flow analysis, mould manufacturing to trial production and mass production, helping customers quickly enter the market and maintain stable quality.

  • Pipe Fitting Injection Mould 04
    Pipe Fitting Injection Mould

    Injection moulds for pipe fittings are primarily used to produce water supply and drainage pipe fittings, irrigation pipe fittings, gas pipe fittings, and industrial pipeline connectors. Common materials include PVC, PP, PE, and PPR. These moulds have relatively complex structures and require extremely high pressure resistance, sealing performance, and dimensional accuracy. They typically utilize high-strength mould steel, precision CNC machining, and optimized cooling systems to ensure uniform wall thickness, stable moulding, and the absence of flash or deformation. Injection moulds for pipe fittings are characterized by high precision and high reliability. Their structural design ensures stable performance in pressure resistance and sealing. The moulds are made of wear-resistant materials and precision-machined, making them suitable for long-term, high-volume production. Furthermore, optimized cooling and the addition of automatic core-pulling and hot runner structures improve moulding efficiency and stability. They exhibit excellent dimensional control, effectively reducing deformation and deviation, ensuring smooth pipe installation. These moulds are widely used in municipal engineering, home decoration piping, agricultural irrigation, industrial fluid systems, and gas transmission and distribution pipelines, meeting the pipe fitting production needs of different regions and standards.

Latest Updates WHAT’S NEWS

  • News Kaiji Mould strictly controls the accuracy of the mould core, with a tolerance controlled within ± 0.01mm

    In order to maintain stable export quality, the company has optimized the mould inspection process, and each set of moulds must undergo three trial moulds and full size inspections before leaving the factory. The mould is made of high-quality steel such as P20, 718H, S136, etc. The polishing and moulding processes are strictly controlled to prevent burrs and misalignment.For long-term cooperation needs of foreign trade customers, we can provide mould quality assurance agreements, steel material reports, and trial mould samples to meet the quality audit standards of European and American customers.


  • News Overcoming the problem of thin-walled deep cavities, Kaiji's thin-walled container moulds for lunch boxes are exported in bulk to Europe and America

    For high difficulty thin-walled products such as fast food boxes, disposable water bottles, and thin-walled storage containers, the company's technical team optimized the exhaust system and needle valve hot runner structure to solve the problems of product shrinkage, warping, and uneven wall thickness.At present, multiple thin-walled lunch box moulds have been steadily mass-produced, with a wall thickness of up to 0.35mm and stable high-speed injection molding, meeting the production requirements of European and American food grade plastic products. Recently, many sets of thin-walled packaging moulds have been successfully sent to customers in Poland and Türkiye, becoming a new growth point of the company's foreign trade.
