How to Help Customers Achieve Full-Process Design Optimization

Helping customers achieve full-process design optimization can comprehensively enhance the market competitiveness of their products or services, reduce costs, and accelerate value delivery.

As a factory focusing on mold manufacturing and injection molding, Kingsjeng supports customers in full-process design optimization from four dimensions: “Design feasibility, Cost control, Production efficiency, and Quality optimization”, combining process experience with specific measures as follows:  

Ⅰ.Early Intervention: Design for Manufacturability (DFM) Analysis

1.Material and Structure Adaptability Assessment

(1) Recommend suitable plastic materials (e.g., ABS, PC, POM) based on product application scenarios, and analyze the impact of material fluidity and shrinkage rate on structural design (e.g., avoid using high-shrinkage PP for thin-walled parts).  

(2) Optimize structural details:  

A. Reduce mold-unfriendly structures like undercuts, acute angles, and deep holes to lower mold processing complexity (e.g., replace integral undercuts with detachable structures).  

B. Suggest reasonable draft angles (typically 1°–3°) and wall thickness uniformity (deviation ≤15%) to avoid shrinkage and warping during injection molding.  

2.Mold Cost and Production Efficiency Prediction  

(1) Recommend mold parting surface design (e.g., planar vs. curved parting) based on product size and precision requirements to reduce mold processing costs.  

(2) Estimate mass production cycle: Shorten injection molding cycle time (e.g., reduce from 40s to 35s for conventional products) through gate position optimization (pin gate/submarine gate) and cooling system design (water channels surrounding the core).  

Ⅱ.Mold Design: Process-Driven Design Optimization

1.Mold Structure Optimization Suggestions

(1) Design insert-molded dies (e.g., half molds, slider structures) for complex products to avoid cracking risks in integral molds.  

(2) Recommend hot runner systems (instead of cold runners) to reduce scrap rate (from 20% to below 5%) and improve melt uniformity.  

2.CAE Simulation for Design Assistance  

(1) Use mold flow analysis (Moldflow) to predict issues like short shots, weld lines, and stress concentration, and adjust designs in advance:  

A.Example: Add process ribs at weldingline positions to enhance strength.  

B.Adjust the number and position of gates to balance melt flow and reduce warping deformation.  

Ⅲ.Trial Molding and Mass Production: Data-Driven Continuous Optimization

1.Rapid Iteration in Trial Molding

(1) Provide full-dimension inspection (CMM measurement) for trial mold samples, and compare deviations from design drawings (e.g., analyze mold wear or shrinkage rate errors when dimensional tolerance exceeds 0.1mm).  

(2) Record injection parameters (temperature, pressure, cooling time) to backtrack design optimization points (e.g., recommend increasing local wall thickness by 0.2mm for edge short shots).  

2.Mass Production Process and Cost Control  

(1) Reduce unit mold cost through multi-cavity mold design (e.g., 8-cavity mold instead of 4-cavity).  

(2) Propose integrated secondary processing solutions (e.g., In-Mold Labeling (IML), two-color injection molding) to reduce post-processing steps (painting, screen printing), lowering comprehensive costs by 10%–30%.  

Ⅵ.Value-Added Services: Full Lifecycle Optimization Support

1.Lightweight Design: Reduce material usage with hollow structures and honeycomb reinforcing ribs while ensuring strength (e.g., 15% weight reduction for car door panels).  

2.Environmental and Compliance Support: Provide recyclable material selection (e.g., rPET) and halogen-free flame-retardant solutions to meet EU/US environmental standards (RoHS, REACH).  

3.Post-Sales Design Iteration: Based on mass production defect data (e.g., batch burrs, deformation), offer mold repair plans (e.g., correct parting surface wear, adjust cooling channels) to continuously improve yield (target ≥98%).  

●Summary: The Core Value of Kingsjeng Injection Molding Factory

Using "mold process + injection molding experience" as a bridge, Kingsjeng transforms customers' design concepts into mass-production solutions with low costs and high quality, enabling end-to-end empowerment from "drawing optimization" to "mass production implementation".
