Each tooling project starts with a review of the part geometry, resin, expected production conditions, appearance requirements, tolerances and the customer’s mold standard. The team checks draft angles, wall thickness, shut-offs, parting lines, ejection, cooling and areas likely to affect filling or deformation. Findings are discussed before the mold concept and quotation scope are confirmed.
The tooling proposal records the agreed mold construction, steel and component standards, planned trials, sample quantities and the process for approving changes. Ownership, storage, maintenance and transfer arrangements are written into the project agreement. During mold manufacturing and trials, open issues, corrections and sample status are tracked against the current approved files.
The tooling team has an average of 20 years of industry experience and provides mold-flow analysis and tooling recommendations based on the product structure and production requirements. Our mold design director has more than 20 years of mold-industry experience, and the mold design engineers each have more than 10 years of experience. Their work covers mold manufacturing processes, injection molding, plastic resin properties, mold steel and component standards including HASCO, DME and MISUMI. The design team uses AutoCAD, Pro/E, SolidWorks and UG, and can work with common project files including DWG, PDF, X_T, IGS and STP.
Our dedicated tooling factory includes high-speed and medium-speed CNC machines, EDM, wire-cutting, grinding, drilling, lathes and milling equipment. High-precision inspection equipment, defined measurement procedures, dedicated molding machines for mold trials, and experienced trial and inspection technicians support the work from machining through sample validation. Keeping these operations connected helps the team control tooling cost, communication and correction cycles.
Quality Standards
- Planning:
Before a mold project begins, experienced engineers hold a project meeting to review the latest part data, resin, target quantities, cosmetic surfaces, critical dimensions and mold requirements. Each mold system and open risk is discussed so that approval points and long-term reliability requirements are clear before machining.
- Material Quality:
Mold steel and mold bases are purchased from established suppliers such as LKM and MINGLEE, with material certificates available for quality verification. Production resin is purchased from original manufacturers, official distributors or customer-approved suppliers according to the approved material specification.
- Heat Treatment:
Where heat treatment is required, the specified steel grade, hardness range and treatment process are confirmed before work begins. Heat treatment is completed by a qualified specialist steel supplier, and the resulting documentation is checked against the approved mold plan.
- Measurement:
Mold steel and critical components are measured after the relevant machining stages to confirm precision before the next operation. After a mold trial, part samples are measured against the supplied drawing, and the agreed results are recorded in the measurement report.
- Workforce and Process Control:
Workers receive process and quality training for machining, EDM, grinding, fitting and inspection. These operations follow the current approved drawings and process requirements, and any revision must be clear to the people carrying out the next operation.
- Quality Assurance:
After each mold trial, the project team reviews the molding conditions, sample results and any issues found during testing. Corrections are agreed, checked in the next trial and followed through until the sample and project status are approved for production.
- Reporting:
Trial observations, molding conditions, sample information, open issues and proposed corrections are reported according to the agreed project scope. Dimensional results are recorded against the supplied drawing so the customer can review changes and approve the next step.
- Quality Control:
Before a mold is packed or released for production, every insert, moving component and assembly detail is inspected. Trial and production parts are checked through the defined process for dimensions, appearance, fit and function rather than being accepted on appearance alone.
