Precision Mold Tooling, Built In-House.
From concept to production-ready tooling, YMS operates a fully integrated mold shop combining expert engineering, advanced CNC/EDM machining, and strict QC -- delivering silicone molds with tolerance ≤ ±0.01 mm.
Our Engineering Team
30+ Senior Mold Engineers, One Shared Standard
Our team brings decades of silicone tooling expertise, with structured roles from DFM analysis to post-trial optimization.
Mold Designers
UG/Pro-E/CAD specialists with 8+ years experience in silicone-specific tooling geometry.
CNC Machinists
Certified operators for 5-axis, 3-axis and high-speed cutting of hardened steels.
EDM Technicians
Precision wire-cut & sinker EDM experts for fine details, ribs, and venting systems.
Fitters & QC
Final assembly, trial-run, and dimensional verification handled by dedicated specialists.
Mold Design Capabilities
DFM-First Engineering, from 2D Sketch to 3D Steel
Every project begins with a thorough Design-for-Manufacturing (DFM) review. Our engineers simulate flow, cure, and shrinkage behavior unique to solid and liquid silicone before cutting a single block of steel.
-
UG, Pro/E, SolidWorks, AutoCAD Full compatibility with client file formats (STEP, IGES, X_T, STL).
-
Mold Flow Analysis & Shrinkage Compensation Predict warpage, flow lines, and curing gradients pre-production.
-
Multi-Cavity & Family Mold Design 1-128 cavity configurations optimized for volume and cycle time.
-
LSR Cold-Runner System Design Zero-waste runnerless tooling for high-end liquid silicone products.
CNC Machining Equipment
High-Speed, High-Precision Metalworking
Our CNC department houses 20+ premium machining centers running 24/5, cutting P20, S136, 718H, and NAK80 tool steels to mirror finish.
5-Axis Machining Centers
Complex contouring, undercuts, and sculpted silicone cores handled in a single setup for maximum accuracy.
High-Speed 3-Axis
Spindle speeds up to 42,000 RPM for mirror-finish cavities, reducing manual polishing by 60%.
Precision Grinders
Surface and cylindrical grinding for parting lines, slide rails, and ejector plates at sub-micron accuracy.
EDM & Precision Machining
Where Steel Meets Micron-Level Detail
EDM (Electrical Discharge Machining) is where fine ribs, intricate textures, and non-cuttable deep cavities come to life. We operate dedicated wire-cut and sinker EDM cells for silicone-specific features such as venting slots, logo embossing, and conformal cooling channels.
Deep ribs, embossed logos, and sharp inside corners.
±0.005 mm precision for inserts, slides, and ejectors.
Mirror-grade EDM finishing minimizes polishing effort.
Automated overnight runs accelerate delivery timelines.
Mold Assembly
Hand-Fitted by Veteran Mold Makers
Every mold is assembled in a dust-controlled fitting bay. Senior fitters polish, blue-match, and verify alignment before first trial.
Component Inspection
All inserts, slides, and ejectors measured on CMM before entering assembly.
Blue-Matching
Parting line contact verified with Prussian blue to eliminate flash risk.
Hand Polishing
Mirror finish (SPI A1/A2) applied by craftsmen with 10+ years experience.
Dry Cycle Testing
Full open/close + ejection simulation prior to loading onto press.
Trial Molding
T1 to T3 Trials -- In-House, Same Facility
Our mold shop sits beside our 64 silicone presses. This means T0 samples can be running within hours of final assembly -- no outside logistics, no delays, no finger-pointing between shops.
Modification & Optimization
Agile Engineering Response to Design Changes
Markets move fast. Our mod team adapts existing tooling to new SKU variants, improves cycle times, and resolves field-feedback issues -- typically within 5-10 working days.
Geometry Revisions
Cavity re-cut, insert swap, or logo updates without rebuilding the full mold base.
Cycle Time Reduction
Conformal cooling, improved venting, and runner balance to cut cycles 10-25%.
Defect Resolution
Address flash, flow lines, or short-shots through targeted mold adjustments.
Maintenance Management
Protecting the Lifetime Value of Your Tooling
Every mold is tracked via our digital tooling management system -- recording shot count, maintenance history, and storage condition. Your investment stays production-ready, every day.
Daily Press-Side Checks
Operators log cycle count and visual inspection every shift.
Scheduled Preventive Maintenance
Deep cleaning, lubrication, and insert inspection every 10,000 shots.
Climate-Controlled Storage
Dehumidified racks prevent oxidation during idle periods between orders.
Full Digital Traceability
Each mold has a QR-coded history file accessible to our clients on request.
Quality Control
Metrology-Backed Confidence
Our QC lab operates independently from production, equipped with CMMs, optical measurement, hardness testers and surface profilometers.
CMM Inspection
Zeiss Contura -- full 3D dimensional verification.
Optical Scanning
Non-contact 3D scan compared vs. CAD master.
Hardness Test
Rockwell + Shore testing of all tool steels.
Full QC Report
Delivered digitally with every mold handover.
