Step 01 -- Intake
Receiving your design, respecting your IP.
Share your 3D files, 2D drawings, mood boards, or hand sketches. We accept projects at any stage -- from early concept to tooling-ready releases.
Signed NDA on request before any file transfer.
3D CAD Files
STEP, IGES, STL, X_T, SolidWorks, Rhino native files all supported.
2D Drawings
Dimensioned PDFs, DWG, DXF with tolerance callouts and GD&T.
Mood & Color
Pantone references, surface finish samples, texture inspiration.
Sketches & Briefs
Early-stage ideas welcome. We help structure them into producible outputs.
Feasibility Report
PASSED-
Wall thickness analysis
Uniform 1.8-2.4mm -- within optimal range.
-
Undercut detection
2 undercuts flagged -- recommend side action mold.
-
Material selection
Suggest LSR 40 Shore A for soft-touch feel.
-
Cost estimation
Target FOB met with 10K MOQ.
Step 02 -- Feasibility
Engineering feasibility, before you commit.
Within 3-5 business days, our engineering team returns a complete feasibility analysis -- wall thickness mapping, undercut detection, parting line proposal, draft angle check, and target cost validation.

Step 03 -- DFM
Design for Manufacturing, hand-in-hand with your team.
We propose structural refinements that preserve your aesthetic intent while unlocking production efficiency. Every DFM note is annotated on your file and reviewed with your design lead.
Draft Angle Optimization
Add minimum 1-3° draft on vertical walls to ensure clean demolding without surface drag marks or whitening.
Parting Line Strategy
Place parting lines along natural edges or texture breaks to keep visible surfaces flawless.
Rib & Fillet Design
Convert sharp corners to generous fillets to improve material flow and reduce stress concentrations.
Gate & Vent Placement
Optimize gate location and venting to eliminate flash, air traps, and weld lines on A-surfaces.
Multi-material Interfaces
Design mechanical locks and chemical bonding zones for silicone-plastic or silicone-metal overmolding.
Tolerance Negotiation
We benchmark every dimension -- tightening what matters, relaxing what doesn't, to meet ±0.1mm where critical.
Step 04 -- Material & Process
The right silicone, the right process.
Based on your product's hardness, transparency, surface finish, and certification needs, we match the ideal silicone grade and molding process -- supported by in-house material testing and 15 years of application data.
Material Grades
- LSR (Liquid Silicone) 10-80 Shore A
- HTV (Solid Silicone) 20-90 Shore A
- Food-grade Platinum Cure FDA / LFGB
- Medical-grade USP Class VI
- Optical / Transparent High clarity
Production Processes
- LSR Injection Molding 32 machines
- HTV Compression Molding 32 machines
- Overmolding (2K / 3K) Multi-material

- Surface Finishing Matte · Gloss · Soft-touch
Step 05 -- Tooling & Prototype
Precision molds. Functional prototypes.
Our in-house tooling workshop builds production-grade molds using S136, 718H, and NAK80 steels. For rapid validation, we also offer 3D-printed and soft-tool prototypes before committing to steel.
Prototype Molds
Aluminum or soft steel tooling for 50-500 units. Lead time 7-12 days for early design validation.
Lead time
7-12d
Steel Production Molds
S136 / 718H / NAK80 hardened steel. Multi-cavity, hot runner, cold runner. Life expectancy 500K+ shots.
Lead time
25-35d
Multi-cavity & 2K Molds
Up to 64 cavities. Combined silicone + plastic / silicone + metal in a single tool for integrated parts.
Lead time
35-50d
Prototype Options
Flexible paths to validate before tooling.
Step 06 -- Sample & Iteration
Test, refine, approve -- together.
First-article samples ship to your studio with a complete QC report. We support up to 3 rounds of mold adjustments before PP samples lock design intent.
First Article Sample
T0 samples with dimensional report, surface finish photos, and material certification.
Design Review
Joint review call. Collect feedback on fit, finish, haptic feel, and visual match.
Mold Refinement
T1-T3 revisions. Polish, EDM, texture, dimension corrections -- included in tooling cost.
PP Sample Sign-off
Pre-production samples sealed as golden reference. Mass production begins only after your approval.
