The following are the main steps to customize plastic injection moulds:
1.Product design and analysis
• Product design: Design the 3D model of the plastic product according to the requirements, clarifying details such as structure, dimensions, and appearance.
• Mouldability analysis: Use mould flow analysis software to analyze the filling, cooling, and warpage of the product in the injection moulding process to optimize the design.
2.Mould design
• Determine the mould structure: Choose the appropriate mould type, cavity number, gating system, ejection mechanism, and cooling system according to the product structure and production requirements.
• Design review: Review the mould design drawings to check for interference, unreasonable structure, and other issues.
3.Mould manufacturing
• Material procurement: Purchase high-quality mould steel and other materials according to the design requirements.
• Machining: Use CNC machine tools and other equipment to process the mould parts to ensure dimensional accuracy and surface quality.
• Heat treatment and surface treatment: Improve the hardness, wear resistance, and corrosion resistance of the mould parts.
• Assembly: Assemble the processed mould parts in strict accordance with the design requirements and adjust the clearance and fit.
4.Mould testing and debugging
• Trial injection: Install the mould on the injection moulding machine, adjust the process parameters, and conduct trial injection to produce sample products.
• Mould debugging: Analyze the quality problems of the sample products, adjust the mould structure and process parameters, and repeat the trial injection until the product quality meets the requirements.
5.After-sales service
• Maintenance and repair: Provide regular maintenance and repair services to ensure the normal operation of the mould.
• Technical support: Provide technical support and solutions for customers' mould use problems.
