Manufacturing Process & Key Features
-
Compression Molding
High-temperature vulcanizing (HTV) silicone sheets are precision-cut and molded in multi-cavity tools under controlled pressure and temperature, ensuring uniform density and dimensional stability. -
Tooling & Mold Fabrication
CNC-machined aluminum or steel molds with EDM-finished cavities ensure precise dome geometry, venting design, and flash-free edges. -
Secondary Operations
-
Laser etching or pad printing for permanent symbols
-
Conductive pill dispensing (carbon or silver-based)
-
Adhesive backing or gasket integration
-
100% tactile and electrical testing
-
-
Surface Finishing Options
-
Matte/Textured Surface – Reduces glare and fingerprint visibility
-
Glossy Finish – Enhances aesthetic appeal for commercial devices
-
Anti-microbial Additives – Available for healthcare or public POS systems
-
Quality Assurance
We enforce a strict quality management system aligned with IATF 16949 and ISO 9001 standards. Each keypad undergoes:
-
Raw Material Inspection – Silicone compound certification and RoHS/REACH compliance validation
-
Dimensional & Visual Checks – 3D optical measurement for key alignment, dome height, and wall thickness
-
Functional Testing – Actuation force profiling, travel distance verification, and life-cycle endurance testing
-
Environmental & Chemical Tests – Thermal aging, UV exposure, wipe tests with alcohol and common cleaners
-
Electrical Validation – Continuity testing for conductive pill keypads; insulation resistance where required
All processes include full traceability and batch-level documentation.
Factory Capabilities
Our facility houses 15–200 ton compression molding presses, CNC and EDM mold-making centers, laser etching systems, and automated dispensing cells. With cleanroom assembly stations, precision die-cutting equipment, and in-house tooling maintenance, we ensure high repeatability and fast turnaround. Our integrated approach—from DFM and prototyping to final packaging—enables us to deliver POS-grade keypads that meet international performance and safety standards.
