Product Description

Plastic Enclosure Electronic Box Injection Molding

The plastic enclosure electronic boxes are among the most critical elements for safeguarding circuit boards, sensors, and other electronic parts, while the main manufacturing technique used for producing this kind of product is injection molding, thanks to its efficiency and precise nature.

Core Mold Design Requirements for Electronic Boxes

Compensation for Dimensional Shrinkage: Based on material shrinkage rate (ABS: 0.5%–0.8%; PC: 0.6%–0.9%), make proper compensation on the mold to make sure that the design of the electronic box is suitable for the internal electronic components (such as PCB board, connectors, etc).
Structure of Waterproof and Sealing Design:
Make grooves for rubber gaskets on the box lid or bottom (groove width 2-3mm, groove depth 1-1.5mm) to meet IP65/IP67 waterproof level.
Use interlocking buckles rather than just screw connection to improve the sealing effect and ease assembly.
Optimization of Draft Angle and Demolding: Set draft angle from 1° to 3° for both the inside and outside of the mold to avoid demolding scratches; if it is a deep-cavity electronic box, adopt core pulling mechanism to facilitate demolding of the complicated structure (such as threaded hole, ribs, etc).
Design of Gating System: Adopt submarine gate or edge gate to prevent appearance defects; for large-sized electronic box, use multi-gate injection molding to improve melt filling and internal stress.
Cooling Channel Design: Ensure even placement of cooling water channels around the cavity mold (from cavity surface 10-15mm) to provide even cooling, prevent warpage, sink marks, and improve process efficiency (10%-20% reduction in cycle time).
