High-quality protective cases begin with precision mold engineering. Our experienced tooling team develops production-ready injection molds that deliver consistent quality, efficient manufacturing, and long service life for OEM and ODM protective projects
Mold Design & Precision Tooling
Precision Tooling Is the Foundation
of Every Successful Phone Case
Every premium phone case starts with a well-designed mold. Even the best product design cannot achieve consistent quality without precision tooling.
At HuaRui, mold design is integrated with our engineering and manufacturing process. Before steel is cut, our engineers evaluate product geometry, material selection, wall thickness, draft angles, gate location, cooling efficiency, and manufacturability. This collaborative approach helps reduce development risks, shorten production lead times, and improve overall product quality.
Whether you are developing a rugged phone case, leather case, MagSafe-compatible case, IML phone case, or hybrid protective case, our tooling solutions are optimized for stable mass production.
Our Phone Case Mold Design Process
Product Design Review
We begin by reviewing your CAD files and product specifications to evaluate manufacturing feasibility.
Our engineering team analyzes:
- Product geometry
- Undercuts and parting lines
- Wall thickness consistency
- Draft angles
- Assembly structure
Design for Manufacturing
A comprehensive DFM review identifies potential production risks before tooling begins.
Our DFM service includes:
- Gate location optimization
- Cooling system recommendations
- Material shrinkage analysis
- Ejection system evaluation
- Mold flow considerations
- Cost optimization suggestions
Mold Structure Design
Based on the approved product design, we develop the complete mold structure.
This includes:
- Mold base selection
- Core and cavity design
- Runner system
- Cooling channels
- Venting design
- Ejection mechanisms
- Slide and lifter systems
Precision Mold Manufacturing
Our tooling workshop utilizes advanced CNC machining, EDM, wire cutting, and precision grinding equipment to manufacture production molds with tight tolerances.
Typical applications include:
- PC phone cases
- TPU cases
- Hybrid cases
- MagSafe phone cases
- Leather-wrapped cases
- IML decorative cases
Mold Trial & Optimization
After tooling is completed, we perform T1 mold trials to evaluate:
- Product dimensions
- Surface finish
- Assembly accuracy
- Flash and sink marks
- Gate performance
- Cycle time
- Overall manufacturability
Necessary adjustments are completed before mass production.
Production Approval & Mass Production
After tooling optimization and customer approval, the project moves into production validation and mass manufacturing.
This stage includes:
- Final sample approval
- Process parameter validation
- Production documentation
- First Article Inspection (if required)
- Mass production launch
- In-process quality control
- Final inspection and global delivery
