Detailed Introduction

This precision injection mold is professionally developed for outdoor industrial plastic structural parts, fully optimized for reinforced flame-retardant PPO/PET materials, meeting outdoor equipment requirements of UV resistance, low temperature resistance, impact resistance and long service life.

The mold adopts standard two-plate fixed-moving mold structure, supporting independent cavity customization for multiple product types shown in the picture: camouflage hunting camera housing, fluid pipeline reducing connectors, filter grid square shells and positioning spacer discs. Each complex component cavity is an independent embedded insert, which can be quickly replaced to switch different product specifications, reducing repeated mold development costs for multi-product workshops. Cavity surfaces support two process options: uniform matte texture etching for direct molding, or ultra-fine polishing as pre-treatment for post water transfer camouflage printing, both optimized to eliminate PPO/PET inherent flow lines and sink marks.

Independent distributed cooling pipelines are laid out for every single cavity, which precisely balance mold temperature during long-cycle high-temperature PPO/PET injection molding, greatly restrain internal stress, large housing warpage and uneven shrinkage unique to PPO/PET reinforced material. Multi-direction slide side core pulling mechanism is integrated to form deep cavity, undercut buckle and multi-port pipeline structures in one molding cycle. Precision interlock slide locking blocks maintain stable clamping force under long continuous production, prevent thin-wall & large-area plastic flash, and extend mold service life under long-term PPO/PET high-temperature processing.

Complete Precision Machining Workflow

1. 5-axis CNC rough milling for mold base outline and large complex cavity rough forming
2. Vacuum stress relief heat treatment to stabilize steel hardness, reduce thermal deformation under long-term PPO/PET high-temperature molding
3. Precision surface grinding to control mold plate flatness and parallelism within ±0.002mm
4. Sinker EDM & wire cut WEDM for ultra-fine deep cavity, undercut and multi-port pipeline contour features
5. Customized surface treatment: matte texture etching / high-gloss pre-polishing for water transfer printing
6. Optional non-toxic anti-corrosion surface coating compatible with flame-retardant PPO and PET outdoor engineering plastics

All mold core, cavity and structural components complete full 3D coordinate measurement inspection to meet strict outdoor equipment plastic part drawing tolerance standards. Full customization is supported based on customer samples or 2D/3D engineering drawings: cavity quantity, mold steel grade, cooling channel layout and cavity surface finish can be adjusted according to PPO/PET reinforcement ratio, outdoor weather resistance grade and daily production capacity. The modular interchangeable cavity layout significantly improves molding flexibility while unifying dimensional consistency and surface quality of all types of outdoor industrial plastic parts.
