Custom injection mold builder, Ningbo (P&M) Plastic Metal Products Co., Ltd. has 18 years of mold manufacturing technology and 10 years of export experience. We provide professional one-stop customized mold services and are a professional plastic mold manufacturer. We can use injection molding, blow molding, die-casting, and rotational molding.
Custom injection mold builder refers to a manufacturing service that specializes in creating tailored molds for producing plastic parts through injection molding. These molds are designed according to the specific requirements of the product, allowing for high-precision shaping and integration of complex features. By using customized molds and processes, this technology can produce plastic components with precise dimensions, intricate structures, and multiple functions in a single molding operation. Compared with metal enclosures, plastic parts made through custom injection molding offer advantages such as lighter weight, greater design flexibility, and better resistance to corrosion. This service is widely applied in consumer electronics, industrial control systems, automotive electronics, medical equipment, and other fields, providing essential protective and structural solutions for various electronic devices.
1 Core Characteristics of Custom injection mold builder
1. High Protection Performance and Structural Reliability
Protection Level Adaptation: Different IP protection levels are achieved through mold design.
Structural Strength Guarantee: Reinforcing ribs are designed at key parts of the enclosure (such as screw columns, interface frames), and glass fiber reinforced plastics are used to make the enclosure's impact strength ≥25kJ/m² and static load-bearing ≥50N;
Installation Precision Control: The dimensional tolerance of the enclosure's installation holes (screw holes, positioning holes) is ±0.02 mm, and the hole coaxiality is ≤0.03mm, ensuring precise docking with circuit boards and radiators (installation gap ≤0.1mm) and avoiding component damage caused by misalignment.
2. Functional Structure Integration and Modular Design
The electronic casing needs to integrate multiple functional interfaces and installation structures, and the injection molding process can achieve modular molding, simplifying assembly:
Interface and heat dissipation integration: The interface holes are integrally formed during the injection molding of the shell, with smooth hole walls and no need for subsequent drilling; Synchronously forming heat dissipation slots or protrusions to improve heat dissipation efficiency;
Internal support structure integration: The shell is integrated with circuit board support columns and component positioning ribs, and the top of the support columns is designed to prevent pressure damage to the circuit board during installation;
3. Material Performance and Electronic Function Adaptation
There are significant differences in the performance requirements of shell materials for different electronic devices, and targeted selection is needed during injection molding to ensure compatibility with electronic functions
Insulation and temperature resistance requirements: Consumer electronics casings are made of ABS or PC to avoid the risk of electrical leakage; Industrial control casing, using PPO/PS, suitable for equipment operation and heat generation;
Electromagnetic shielding requirement: The communication equipment casing must have electromagnetic shielding function.
Transparency and appearance requirements: The display device shell should be made of transparent PC, and the surface should be treated with scratch resistance; The exterior components are made of PC/ABS alloy and achieve multi-color effects through dual color injection molding or surface spraying, meeting the aesthetic needs of consumer electronics.
II Production Process of Plastic Injection Moulding Electronics Enclosure
1. Product Design and Mold Development
(1) Product Design
Structural design: Draw a 3D model using CAD software, focusing on the design of shell wall thickness, sealing groove size, and heat dissipation structure layout; Annotate key dimensional tolerances;
(2) Mold development
Mold material: The appearance mold is made of S136 stainless steel; H13 hot work die steel is selected for the structural component mold;
Mold cavity design: Multiple mold cavities are used, with symmetrical layout to ensure uniform filling; For complex structures, a core pulling mechanism is adopted to ensure complete molding;
