Plastic Injection Moulding Electronics Enclosure

Plastic Injection Moulding Electronics Enclosure refers to a manufacturing technology that produces plastic enclosure components for protecting electronic components through plastic injection molding processes, with functions of protection , structural support and electromagnetic shielding. Its core feature is realizing high-precision structural molding of the enclosure and complex function integration through customized molds and processes, and adapting to the installation needs of different electronic devices . Compared with metal enclosures, plastic electronic enclosures have the advantages of lightweight, flexible design and corrosion resistance. They are widely used in consumer electronics industrial control, automotive electronics, medical equipment and other fields, and are key protective carriers for the safe and stable operation of electronic devices.

P&M Plastic Injection Moulding Electronics Enclosure Introduction

1 Core Characteristics of Plastic Injection Moulding Electronics Enclosure

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;

2. Raw Material Preparation and Injection Molding

3. Post-Processing and Quality Inspection
