Quality Assurance & Compliance
At 3DOTECH, quality is not an end-of-line checkpoint — it is a discipline enforced at every stage of production, from raw material intake to final outbound shipment. Our multi-stage QA framework, compliant materials, and certified export standing ensure that every product we deliver meets the standards global buyers demand.
Multi-Stage Quality Control System
3DOTECH operates a three-tier quality control system that covers the full production lifecycle. Non-conforming materials or parts are flagged and quarantined at each gate — preventing defects from propagating downstream and protecting the integrity of every finished batch.
| QA Stage | Full Name | When Applied | What Is Controlled |
|---|---|---|---|
| IQC | Incoming Quality Control | Upon receipt of all raw materials | Silicone grade, hardness, color consistency, material certifications, and supplier documentation are verified before any material enters production |
| IPQC | In-Process Quality Control | During molding and vulcanizing operations | Dimensional sampling, cycle parameter monitoring, part appearance inspection, and first-article verification at each production stage to catch deviations in real time |
| FQC / OQC | Final & Outgoing Quality Control | Post-production, prior to packaging and shipment | Full-batch dimensional audit, visual defect inspection, functional testing where applicable, and shipment quantity verification against the purchase order before goods are cleared for dispatch |
STAGE 1 IQC Raw Material Intake | → | STAGE 2 IPQC In-Process Production | → | STAGE 3 FQC / OQC Final Inspection & Shipment |
Material Certifications & Regulatory Compliance
All silicone materials used in 3DOTECH production are sourced from verified, high-grade suppliers and meet the regulatory requirements of major international markets. Whether your products are destined for food contact, consumer electronics, or general industrial use — our material compliance covers you.
| Standard | Issuing Authority | Applicable Market | Scope |
|---|---|---|---|
| FDA | U.S. Food & Drug Administration | United States | Food-contact safety; silicone materials are non-toxic and safe for direct food/beverage contact |
| LFGB | German Food & Feed Code | European Union (Germany-led) | Stricter EU food-contact standard; confirms absence of harmful migration substances in silicone |
| RoHS | European Union Directive | European Union & Global | Restriction of hazardous substances (lead, mercury, cadmium, etc.) in electronic and electrical products |
| REACH | European Chemicals Agency (ECHA) | European Union & Global | Registration, evaluation, and authorization of chemical substances; confirms material safety across the full product supply chain |
Chinese Government Export License — Verified & Current
3DOTECH is an officially registered manufacturer holding a valid export certificate issued by the Chinese government. This legal standing ensures that all international shipments are processed through transparent, fully documented customs channels — eliminating regulatory risk for our import-side clients and accelerating clearance in destination markets worldwide.
Quality Testing Equipment
Consistent quality requires consistent measurement. Our QA laboratory is equipped with industry-standard precision instruments that provide objective, quantifiable verification of every critical product parameter — from dimensional accuracy to mechanical performance.
| Instrument | What It Measures | Why It Matters |
|---|---|---|
| 2D Measuring Machine | Flat-plane dimensions, hole positions, profile tolerances | Rapid, high-accuracy 2D inspection for parts with flat geometries and critical positional requirements |
| 3D Coordinate Measuring Machine (CMM) | Full three-dimensional geometry, complex surface profiles, GD&T parameters | Confirms that complex molded parts meet 3D design specifications with micron-level accuracy |
| Durometer (Shore Hardness Tester) | Shore A/Shore D hardness of silicone and plastic materials | Verifies that material hardness matches specification — critical for functional feel, seal performance, and end-use suitability |
| Tensile Strength Tester | Elongation at break, tear strength, tensile load capacity | Confirms mechanical durability of silicone products under stress — essential for parts subject to stretching, pulling, or repeated flexing in end-use environments |
Our Quality Commitment to Every Client
Every shipment that leaves 3DOTECH has passed a documented, multi-stage quality process — verified by calibrated instruments, controlled by trained QA personnel, and backed by internationally recognized material compliance standards. We do not ship products we would not approve ourselves. That is the standard we hold, on every order, for every client.
