1. Project Background & Customer Pain Points
Project Background
The customer, a well-known international automotive enterprise with cooperation with Dimud (including brands like Mercedes-Benz, Toyota and Jaguar in Dimud’s portfolio), launched a new NEV model in 2025, focusing on lightweight, safety and intelligent experience. The interior and exterior key components (instrument panels, lamp housings, bumpers) are core to the model’s performance, requiring high-precision molds and customized precision components with strict material and process requirements. The customer listed Dimud as a core partner after evaluating its ISO9001, IATF16949 certifications and rich automotive industry case experience.
Core Customer Pain Points
- Tight project cycle: The new model is scheduled for a global launch, requiring mold development and sample confirmation in 45 days (industry average is 60-70 days), with no room for delay.
- Ultra-high precision requirements: NEV component assembly has zero tolerance for errors; machining tolerance of metal and plastic parts needs to reach ±0.01mm, and mold surface finish must meet automotive-grade high standards.
- Material & performance balance: Exterior parts (bumpers) need lightweight materials while ensuring impact resistance; interior parts (instrument panels) require environmental protection, flame retardancy and scratch resistance, with no compromise on any performance indicator.
- Stable mass production capacity: After sample confirmation, the customer needs a monthly supply of 50,000 sets of components, requiring the supplier to have large-scale intelligent manufacturing capacity and a perfect supply chain system.
- Cost optimization: Under the premise of meeting all technical requirements, the customer expects to reduce the overall production cost of molds and components by more than 20% compared with the previous supplier.

2. Dimud’s Customized Solution & Implementation
Combined with its core advantages of “design-mold-manufacturing” integration and one-stop supply chain services, Dimud set up a dedicated project team (PM + R&D + engineering + production + QC) for the customer, and formulated a phased implementation plan with early design involvement, to solve all pain points one by one.
Phase 1: Early DFM Analysis & Design Optimization (Days 1-7)
Dimud’s Shenzhen R&D design team intervened in the customer’s product design stage in advance, conducted a comprehensive DFM (Design for Manufacturability) analysis on the original drawings of instrument panels, lamp housings and bumpers, and put forward 18 optimization suggestions:
- Simplified the complex undercut structure of the lamp housing mold to reduce processing difficulty and shorten production cycle.
- Optimized the material selection of bumpers (adopted automotive-grade modified PP material) to achieve lightweight (weight reduction by 15%) while ensuring impact resistance.
- Adjusted the structural design of the instrument panel to realize integrated molding, reducing the number of assembly parts by 8 and improving assembly efficiency.
All optimization suggestions were confirmed by the customer’s technical team within 2 days, and the final 3D design model was locked, laying a solid foundation for subsequent mold development.
Phase 2: High-Precision Mold R&D & Machining (Days 8-35)
Dimud’s Dongguan Qingxi production base (plastic injection factory + CNC machining factory) undertook the mold R&D and machining work, with core implementation measures:
- Equipment selection: Adopted 5-axis CNC machining centers (tolerance accuracy up to ±0.005mm) for mold core and cavity machining, ensuring the ultra-high precision requirements of ±0.01mm.
- Material control: Selected P20 and H13 automotive-grade mold steel, with surface hardening and polishing treatment, to improve mold service life (up to 500,000 shots).
- Process optimization: Adopted “rough machining → semi-finish machining → heat treatment → finish machining → precision detection” full-process closed-loop processing, with 3-time precision inspection in the middle to avoid defective products.
- 2K mold technology application: For the instrument panel with double-material requirements, Dimud applied its mature 2K mold technology to realize one-time integrated molding, avoiding secondary bonding and improving product consistency.
Phase 3: Mold Testing & Sample Mass Production (Days 36-45)
- Mold testing: Conducted T1-T3 mold testing for all molds, adjusted processing parameters in real time according to test results, and optimized the mold ejection system and cooling system to ensure stable product molding.
- Sample inspection: Dimud’s QC team conducted a full-item inspection on the samples (dimensional accuracy, material performance, surface finish) with high-precision testing equipment, and issued a formal QC report that met IATF 16949 standards.
- Sample confirmation: The first batch of qualified samples was delivered to the customer for assembly testing, and passed the customer’s factory acceptance in 3 days, achieving the goal of “45-day sample confirmation” as scheduled.
Phase 4: Mass Production & On-Time Supply (After Day 46)
Based on its 10,000 ㎡ smart manufacturing base and one-hour supply chain system, Dimud realized stable mass production and on-time supply:
- Opened a dedicated production line for the customer, with 30+ plastic injection machines and CNC machines running 24 hours a day, meeting the monthly supply of 50,000 sets of components.
- Utilized the advantage of “1 hour cross-border land transport from Dongguan to Hong Kong”, realized sea-air intermodal transport, and delivered products to the customer’s global assembly plants (Europe, Southeast Asia) on time.
- Established a real-time supply chain information system, sharing production progress, inventory status and logistics information with the customer, to realize transparent supply chain management.
