Drawings, Samples & Requirements.
Every project begins with understanding. We accept 2D/3D drawings, physical samples, hand sketches, or verbal concepts -- and translate them into manufacturable mold specifications.
2D / 3D Drawings
STEP, IGES, STL, DWG, PDF formats accepted with NDA protection.
Physical Samples
Reverse-engineered through 3D scanning for exact dimensional capture.
Concept Sketches
Hand drawings or ideas developed into full engineering drawings by our team.
NDA & IP Protection
Confidentiality agreements signed before any file exchange or review.
Mold Type Selection.
The right molding process defines product quality, cost, and production efficiency. We help you choose between solid and liquid silicone tooling based on part geometry and volume targets.
Solid Silicone (HTV) Compression Molds
Ideal for pacifiers, teethers, bibs, and larger structural parts. Cost-effective for medium runs with excellent surface finish options.
- Single / multi-cavity designs
- P20 / S136 / NAK80 steels
- 500,000+ shot lifespan
Liquid Silicone (LSR) Injection Molds
Perfect for high-precision, high-volume parts: bottle nipples, soft valves, complex geometries, and overmolded components.
- Cold runner / fully automated
- Micro-tolerance, flash-free
- Overmolding (silicone + plastic/metal)
Mold Structure & Cavity Planning.
Engineering optimal cavity layout, gating, venting, and cooling to balance cycle time, part quality, and tooling cost -- tailored to your annual volume projection.
Cavity Count Analysis
Volume forecast drives 1-cavity, 4-cavity, 8-cavity, or 16+ cavity decisions for optimal unit economics.
Gating & Runner Design
Hot runner, cold runner, pin-point, or submarine gate selection to minimize witness marks on visible surfaces.
Ejection & Parting Lines
Strategic parting line placement and ejection method to preserve aesthetic quality on consumer-facing surfaces.
Cooling & Venting
Balanced cooling channels and micro-venting ensure dimensional stability and consistent curing cycles.
Mold Design Review.
A rigorous multi-stage review process involving our engineering team and your technical representatives -- ensuring every detail is validated before steel is cut.
DFM Analysis
Design for Manufacturing report highlighting wall thickness, undercuts, draft angles, and shrinkage compensation.
Mold Flow Simulation
Virtual filling, packing, and warpage prediction using Moldflow to pre-empt defects before machining.
Client Sign-Off
Formal written approval of final 3D mold design, material specs, and projected lifespan before fabrication begins.
Mold Machining & Assembly.
State-of-the-art CNC, EDM, and precision grinding deliver mold components with sub-micron accuracy. Expert fitters assemble, polish, and dry-cycle test each tool.
Trial Molding & Revisions.
T1, T2, T3 trial shots validate the mold against your product specification. Any required modifications are refined until first-article approval is achieved.
First Trial Shot
Initial sample production, full dimensional and functional inspection against drawings.
Adjustment Trial
Minor cavity adjustments, gate repositioning, or surface refinements performed and re-tested.
Validation Trial
Final verification run, performance tests (tensile, aging, tear) submitted with sample set.
First Article Approval
Signed client approval of samples triggers transition into mass production.
Mold Confirmation & Ownership.
Clear documentation of mold ownership, specifications, and intellectual property rights. Transparent terms protect your investment and brand.
Mold Ownership Certificate
Formal document confirming client owns tooling after full payment.
Full Technical Documentation
Mold drawings, steel certs, cavity ID, and inspection reports.
IP & Confidentiality
NDA ensures designs are never shared or used for other clients.
Mold Maintenance & Storage.
Protect your tooling investment with a scheduled maintenance program and climate-controlled long-term storage facility.
Scheduled Servicing
Routine cleaning, lubrication, and inspection every production cycle to extend mold life.
Climate-Controlled Storage
Rust-proof packaging and humidity-controlled warehouse for molds in dormancy periods.
Lifecycle Logs
Digital tracking of shot count, service history, and remaining useful life for every mold.
Repair & Refurbishment
In-house re-polishing, insert replacement, and cavity restoration to prolong tool lifespan.
Shot Count Monitoring
Automatic counters inform proactive maintenance before any quality drift occurs.
Dormant Mold Protocol
Molds inactive beyond 90 days receive deep cleaning and anti-corrosion treatment before storage.
