Quality Control

End-to-end quality control: precision at the core, quality first.

Four-Stage Quality Inspection Process

From raw materials to finished product, every stage is strictly controlled.

STEP 01

Incoming Quality Control

Verify raw material specifications against drawings to ensure grade and dimensions match requirements, ensuring quality from the source.

STEP 02

Process Review

The technical team reviews and optimizes the machining plan, finalizing clamping methods, cutting parameters, and inspection plans to ensure process feasibility.

STEP 03

Process Inspection

Perform dimensional and geometric tolerance inspections at critical process steps to promptly detect and correct deviations, preventing batch-level issues.

STEP 04

Finished Product Inspection

Perform final full-dimension inspection on finished products using precision equipment such as CMMs, generate inspection reports, and ensure every product meets quality standards.

Detect Device

Equipped with precision instruments for accurate testing.

Coordinate Measuring Machine

Coordinate Measuring Machine

Full-scale precision inspection for complex parts, ensuring geometric tolerances and dimensional accuracy.

Altitude Gauge

Altimeter

Precision measurement for flatness, height differences, and other parameters.

Roughness Tester

Roughness Meter

Precision measurement for surface roughness to ensure quality compliance.

Caliper/Micrometer

Caliper / Micrometer

High-precision measurement tool for everyday precision needs

Confidentiality Management System for Drawings

Comprehensive confidentiality system to ensure your peace of mind when submitting designs.

We understand that custom parts involve your core designs, making blueprint security a key factor in choosing a partner. We have established a comprehensive confidentiality management system and can sign formal NDAs with clients to ensure the safety of your technical data at an institutional level.

Supports signing formal NDA for blueprints, allowing research clients to collaborate with peace of mind.

Sign Non-Disclosure Agreement

Sign a formal Non-Disclosure Agreement (NDA) with the client to define confidentiality scope and responsibilities.

Blueprint Classification Management

Categorize received drawings and documents, and restrict access accordingly.

Secure Storage

Secure storage of drawings and documents; disposal per agreement upon project completion.

Personnel Confidentiality Awareness

Relevant personnel must sign confidentiality agreements and undergo regular confidentiality awareness training.

Quality Control System

We have established a comprehensive quality control system covering the entire process, from incoming inspection to final delivery. Each stage adheres to clear quality standards and testing specifications. Our technical team engages in quality planning during the process review phase, developing tailored inspection plans for each component to ensure critical dimensions and geometric tolerances are effectively controlled.

Designed for industrial clients and single-product prototyping needs, we uphold the highest standards in every machining project. Whether for one-off prototypes or mass production, quality control remains consistent.
