Real Mold Projects. Real Problems Solved. Predictable Outcomes Delivered.
Explore how HST helps EU/UK buyers reduce lead-time uncertainty, stabilize quality from trial to production, and keep launches on schedule.
Real project: Complex automotive housing with controlled lead time and zero trial corrections.
Who They Are & Why Timing Mattered
Understanding the customer's constraints is the first step to delivering the right solution. This wasn't just about making a mold—it was about protecting their production schedule.
Customer Type
EU automotive Tier 1 supplier with strict OEM delivery schedules and internal quality gates.
Product Application
Structural housing for automotive electronics—functional part with tight dimensional requirements and long-term durability needs.
Project Constraints
Fixed production launch window, multi-stage approval process, and zero tolerance for delays that could impact OEM commitments.
What This Customer Was Struggling With
These weren't theoretical problems—they were daily frustrations that created internal pressure and threatened the production timeline.
What "Success" Looked Like for This Project
Clear acceptance criteria remove ambiguity and create shared accountability. Here's exactly what the customer needed to approve the mold.
Timeline Targets
| T0 (Kickoff to Design Approval) | 2 weeks |
| T1 (Design to First Trial) | 6 weeks |
| T2 (Trial to Final Approval) | 1 week max |
| Total Project Duration | 9 weeks |
Quality Acceptance Criteria
-
Critical Dimensions±0.03mm on mounting features and mating surfaces
-
Surface FinishVDI 24-27 on visible surfaces, no sink marks or flash
-
RepeatabilityCpk ≥ 1.33 on critical features over 30 consecutive shots
-
Trial ApprovalPPAP Level 3 documentation with customer-witnessed trial run
Communication Requirements
Milestone completion status, next steps, and any risks identified
Technical questions answered within one business day with clear recommendations
All design modifications logged with technical rationale and customer approval
Our Solution: Engineering-First Execution
We didn't just build a mold—we built a controlled process that protected the customer's timeline and reduced their internal coordination burden.
Engineering-First DFM
We identified 4 critical risks during DFM review before steel cutting: gate location affecting weld line strength, cooling imbalance risk, ejection interference, and parting line flash potential. Each was addressed with alternative designs and simulations.
Milestone-Based Planning
Every week had defined deliverables: Week 1-2 DFM and design approval, Week 3-4 steel procurement and roughing, Week 5-6 precision machining and EDM, Week 7-8 assembly and internal check, Week 9 trial and approval. Customer received photo updates at each gate.
Factory-Direct Control
All critical operations—steel machining, EDM, polishing, and assembly—performed in-house with our own equipment and trained technicians. No outsourcing of core steps. Single engineering contact owned the entire project from design to delivery.
From Inquiry to Delivery: 8 Weeks, Zero Surprises
Predictability comes from visibility. Here's exactly how the project progressed from first contact to approved mold.
Total Project Time: 8 Weeks (1 Week Ahead of Target)
The customer's internal target was 9 weeks. We delivered in 8 weeks with zero trial corrections, protecting their production launch schedule and eliminating approval delays.
Before vs. After: What Changed for the Customer
Success isn't just about delivering a mold—it's about eliminating the problems that were causing daily pressure on the procurement and engineering teams.

Internal CoordinationMinimal coordination burden—clear documentation enabled smooth approvals
Quantified Results
Evidence: How We Document Quality & Control
EU procurement teams need evidence, not promises. Here's what we provide to prove engineering discipline and process control.
Risk identification, design alternatives, and customer-approved decisions documented before steel cutting
CMM measurement reports for critical features with actual vs. nominal comparisons and Cpk calculations
Process parameter sheet, cycle time recording, sample inspection results, and photo evidence of surface quality
Weekly visual updates showing machining completion, assembly stages, and quality checkpoints
Steel mill certificates with heat number traceability for core, cavity, and insert materials
Mold setup instructions, recommended injection parameters, maintenance schedule, and spare parts list
Why Documentation Matters
For EU buyers, proper documentation isn't "extra paperwork"—it's what enables smooth internal approvals, reduces quality disputes, and supports long-term production stability. We treat documentation as part of the engineering deliverable, not an afterthought.
