Preparation Matters for Synchronous Development of New Product Injection Molds

Synchronous development of new product injection molds means parallel progress of product structure design, mold design and process evaluation. It shortens project cycle and avoids mass modification and delayed delivery caused by late-stage risk exposure. Adequate early preparation is the core premise of efficient synchronous development.

1. Pre-Evaluation of Product Moldability

In the early stage of project development, complete moldability evaluation is carried out for unfinished product structures. Check wall thickness uniformity, fillet, draft angle, stiffener, buckle and boss structure. Eliminate unreasonable structures such as sharp corners, sudden wall thickness changes and inverted undercuts that are not conducive to molding. Confirm appearance requirements, parting line position and gate trace standards. Optimize excessive tolerance requirements and feed back structural modification suggestions in advance to reduce later mold changes.

2. Sorting of Project Boundaries and Technical Documents

Complete technical input files including 3D models, 2D drawings, tolerance standards and material parameters must be sorted out. Clarify raw material grade, modification status, annual output, cavity quantity and mold life standard. Define trial mold standards, acceptance specifications and responsibility division for modification changes. Unify all verbal communication into formal technical documents to avoid information deviation caused by asynchronous updates.

3. Mold Scheme Discussion and Risk Prediction

Before detailed mold design, organize scheme demonstration to confirm cavity layout, parting surface, gate type and ejection mode. Evaluate the feasibility of sliders, lifters and hot runners for special structural products. Conduct pre-mold flow analysis to predict welding lines, air traps and warpage risks, and formulate optimization schemes in advance. Evaluate machining difficulty of tiny and deep cavity features to avoid processing dead ends and delayed delivery.

4. Preparatory Work for Procurement, Process and Inspection

Sort out mold steel, standard parts, hot runner and electrical components in advance to lock supply cycle. The process team pre-judges material fluidity, drying parameters and molding equipment matching conditions. The inspection team formulates dimension detection schemes, tool configuration and appearance inspection standards. Complete raw material preparation and equipment debugging before trial molding to ensure smooth sample verification and mass production docking.

Summary

Synchronous development of new molds relies on full early preparation. Moldability evaluation eliminates structural inherent defects, complete technical input ensures accurate design, scheme demonstration avoids molding risks, and pre-layout of procurement and process ensures stable project progress. Standardized early preparation greatly reduces modification frequency, shortens development cycle and realizes fast and high-quality launch of new products.
