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.

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.

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.

Automotive injection moulds are primarily used to produce interior and exterior automotive parts, instrument panels, bumpers, door panels, air conditioning vents, and various functional plastic components.

These moulds require extremely high dimensional accuracy, structural strength, and surface finish, meeting the stringent assembly and durability standards of the automotive industry.

Kaiji utilizes high-strength mould steel, precision machining equipment, and an optimized cooling system to ensure long mould life, stable moulding, and superior appearance quality.

Customized hot runner systems, automatic core pulling, and special textured structures can be tailored to different vehicle models and production needs, achieving high-efficiency, low-scrap production to meet the demands of mass production and diverse market demands.

Double-Color injection moulds can simultaneously mould two different colors or materials in a single injection process, enabling complex patterns, Double-Color combinations, and functional integration.

The mould structure is complex, typically employing a precision dual-gutter system and a high-precision core cavity design to ensure accurate positioning of the two materials, preventing color bleeding and porosity.

Double-Color moulds offer high production efficiency, reducing subsequent painting or assembly steps and improving overall processing efficiency.

The moulds are durable and suitable for mass production, and can be customized to meet specific customer needs, including combinations of hard and soft materials, textured effects, or special functional parts.

They are widely used in electronic product casings, automotive interior parts, home appliance buttons, and everyday consumer goods.
