SERVICE SCOPE & CAPABILITIES
Mold Trial Types We Run β T0, T1, T2, PPAP & Scientific Molding
Structured sampling is the difference between a mold that ships and a mold that haunts production. Every milestone we run produces documented evidence: fill-pattern photos, CMM dimensional data, root-cause defect diagnosis and a locked process window.
T0 β FIRST TRYOUT
Initial Machine Tryout
- Mold mounted, aligned and clamped on an in-house injection machine (30β650 ton)
- Cavity fill pattern, gate balance and venting verified shot by shot
- Ejection system validated β no stuck parts, no ejector damage
T1 β CORRECTED SAMPLING
Post-Correction Dimensional Validation
- Corrected samples measured on ZEISS CMM against a ballooned drawing
- Flash, sink marks, weld lines and warpage re-checked after every correction
- T1 report delivered with photos, defect diagnosis and corrective-action log
T2 β PROCESS TUNING
Production Process Window Lock
- Injection pressure, melt temperature and cycle time optimized for stability
- Dimensional repeatability confirmed across consecutive shots
- Process window documented for clean transfer to mass production
PPAP & TF β FINAL APPROVAL
PPAP-Ready Final Sampling
- Sampling against a PPAP-style checklist: steel certificates, hardness logs, CMM report
- Capability (CPK) data on critical dimensions where the program requires it
- Customer sign-off package with full dimensional and material documentation
SCIENTIFIC MOLDING
Data-Driven Process Validation
- Instrumented trials with melt temperature, pressure and fill-time data
- Cavity pressure curves used to set robust, repeatable process windows
- Gate freeze and venting behavior analyzed from data instead of guessed
CUSTOMER-SUPPLIED MOLDS
Independent Mold Validation
- Trial and validation of molds built by other factories
- Neutral defect report with photos so you can enforce corrective action
- Second-opinion sampling for mold acceptance disputes
ENGINEERING & TRIAL PARAMETER OPTIMIZATION
Trial Parameter Engineering & DFM Support
Most trial rounds are lost before the mold reaches the machine β wrong gate position, weak venting, unbalanced cooling. We review the design, set the trial parameters and document every correction so your sampling converges in the fewest rounds.
What We Optimize Before the First Shot
Gate, Runner & Venting Review
Gate position and size, runner balance and venting depth reviewed against part geometry to prevent short shots, weld lines and trapped gas at T0.
Cooling & Cycle-Time Optimization
Cooling channel layout and mold temperature recommendations that cut cycle time while controlling shrinkage, sink marks and warpage during sampling.
Ejection & Draft Verification
Draft angles and ejector layout checked to avoid sticking, ejector marks and distortion β the most common T0 failures on A-surface parts.
Shrinkage & Tolerance Risk Mapping
Expected shrinkage per resin and tolerance risk areas mapped before the first shot so T1 dimensions land inside drawing tolerance in fewer correction loops.
Six-Step Trial Execution Flow
CAD & Material Review
Part drawing, resin data sheet and mold design reviewed before the trial is scheduled.
Trial Plan & Parameter Sheet
Machine, tonnage, melt temperature and fill-speed plan agreed with your team.
T0 First Tryout
Fill pattern, gate balance and ejection verified on the machine, shot by shot.
Defect Diagnosis & Mold Correction
Root-cause analysis with photos; mold corrected (e.g. parting line 0.05β0.015 mm) and re-run.
T1 Dimensional Report
Full CMM measurement against drawing with flash, finish and warp data documented.
T2/Tf Sign-off & Handover
Process window locked, samples approved and documentation pack handed over for PPAP.

INDUSTRY CASES
Case Studies for Mold Trial & T1 Sampling

Automotive Interior Program Β· Tooling + Process Fix
Eliminating Ejector Pin Marks on an Automotive Door Panel
A 1,400 g PP door panel came off the mold with circular ejector marks on the A-surface. Fixed at tooling level (draft, rib polish, ejector layout) and process level (holding pressure and time) β a textbook T1 correction loop.

Kitchen Appliance OEM Β· Prototype Tool Rebuild
Sequential Multi-Slider Mold for a Kitchen Appliance Water Manifold
Thin-wall ribs dragged and deformed on the prototype tool. The action sequence was rebuilt around hydraulic cylinders and per-slider cooling until T1 samples held drawing tolerance.
FREQUENTLY ASKED QUESTIONS
Mold Trial & T1 Sampling β Process, FAQ & Quote
Common questions about mold trial milestones, sampling reports, machine rates and mold acceptance β answered by our process engineers.
T0 is the first machine tryout to verify cavity fill and ejection. T1 is sampling after the first correction round, with full dimensional validation. T2 is process tuning for stable, repeatable production. Final approval (Tf) closes the loop with PPAP-style documentation and customer sign-off.
A typical T0 tryout runs 1β2 days on the machine. The full T0βT1βT2 sequence usually takes 1β3 weeks depending on how many correction loops the mold needs β parallel scheduling and priority correction loops keep tight deadlines on track.
Short shots, flash, sink marks, warpage, weld lines, gas traps and ejection issues β each documented with photos, root-cause analysis and the exact corrective action taken, so the fix is repeatable.
Yes β every sampling round includes CMM measurements of critical dimensions against a ballooned drawing, plus steel certificates, hardness logs and a sample inspection report.
Yes. We sample against a PPAP-style checklist and provide capability (CPK) data on critical dimensions where the program requires it β the same documentation tier as Tier-1 and OEM sampling.
Yes. We run trial and validation for customer-supplied molds, with a neutral defect report including photos so you can enforce corrective action or approve production with confidence.
Both options are available. Simple T0/T1 rounds are usually quoted per sampling round or per machine hour; multi-round PPAP programs get a fixed project quote with a defined milestone schedule.
