MOLD DESIGN & MANUFACTURING
For precision injection molds, die-casting molds, MIM / PM molds and dedicated fixtures, we provide DFM review, mold engineering, precision manufacturing, trials, correction, maintenance and production-launch support.
Process-led, Production-ready
DFM-led planning for mold accuracy, service life, cycle time and long-term maintainability.
MOLD DESIGN & MANUFACTURING OVERVIEW
A complete engineering approach connecting product structure, forming method, dimensional stability, appearance requirements and production cycle time.
Production-oriented mold engineering begins with the requirements of the finished part, including dimensions, appearance, assembly relationships and cycle time. Parting, gating, venting, cooling, ejection and downstream machining datums are evaluated in advance.
Zhongde Precision integrates mold engineering with forming, CNC machining, surface finishing and assembly. Mold-trial results can therefore be fed back quickly into correction, while dimensional stability and manufacturing feasibility are verified before production launch.
MOLD & TOOLING SCOPE
Precision injection, aluminum and zinc die-casting, MIM / PM molds and dedicated tooling, with mold structures and manufacturing routes selected according to product geometry, material, volume and forming conditions.
01INJECTION MOLD
For engineering plastics, precision structural parts and appearance components, with early evaluation of parting, gating, venting, cooling, ejection and dimensional stability.
02ALUMINUM DIE CASTING
Engineering of filling paths, overflow and venting systems, mold thermal balance and release conditions for complex structures and stable production.
03ZINC DIE CASTING
For thin-wall precision parts and complex appearance structures, with emphasis on filling, flash, parting-surface wear and continuous-production stability.
04MIM / PM & TOOLING
MIM injection molds, PM compaction tooling, and dedicated fixtures and gauges used for machining, inspection and assembly.

MOLD WORKSHOP & EQUIPMENT
A dedicated 500 m² mold workshop with 11 machines for mold-component machining and tooling production, covering precision cutting, EDM, wire cutting, correction and maintenance.
Processes deep cavities, narrow slots, sharp corners and complex mold features that are difficult to cut conventionally.
Produces wire-cut starting holes, small holes and deep holes for subsequent EDM and wire-cut operations.
Cuts inserts, slides, punches, plates and high-precision contours, including hardened mold materials.
Machines cores, cavities, mold bases, inserts and mechanism components through milling, drilling and finishing.
Machines round parts, auxiliary structures and repair components, and supports mold correction and adjustment.
Produces tooling base plates, sheet-metal parts, templates and auxiliary fixtures for rapid tooling preparation.
DESIGN VALIDATION & CAE SIMULATION
Before mold machining, filling, air-entrapment, venting, shrinkage, cooling and deformation simulations are performed according to product geometry, material, molding process and critical quality requirements. Engineering validation helps optimize gates, runners, vents, cooling circuits and mold structures in advance, reducing mold-trial corrections.
Evaluates filling sequence, flow balance, pressure distribution, flow-front movement and short-shot risk.
Output: gate, runner and filling-sequence optimization
Identifies trapped-air locations, venting dead zones and end-of-fill regions, and checks whether venting paths are effective.
Output: vent locations, vent grooves and overflow recommendations
Predicts flow-front meeting locations and evaluates weld-line risks affecting appearance, strength and critical areas.
Output: gate-location and weld-line improvement plan
Evaluates packing effectiveness, volumetric shrinkage, sink-mark risk, internal stress and dimensional variation.
Output: packing conditions and dimensional compensation
Analyzes mold-temperature distribution, local hot spots, cooling time and temperature differences.
Output: cooling-circuit and thermal-balance optimization
Predicts warpage caused by uneven shrinkage, material orientation and cooling differences, while checking mold-structure risks.
Output: deformation compensation and mold-structure optimization
Simulation items are selected according to product complexity, material behavior, molding risk and customer requirements.
