BSP – Professional Product Inspection & Fixturing Solutions

BSP boasts a comprehensive product inspection system and advanced testing equipment, specializing in the design and manufacturing of high-precision inspection fixtures and product positioning jigs . We strictly adhere to customer drawings, conduct CPK/PPK statistical analysis , and provide complete FAI (First Article Inspection) reports , delivering robust data support and standardized production criteria for mold acceptance—ensuring consistent quality control throughout the process.

Key Advantages:
✔ Precision Inspection : ±0.01mm repeatability for diverse testing needs.
✔ Data-Driven : CPK/PPK analysis enhances process stability.
✔ End-to-End Service : From design to manufacturing and report delivery, supporting efficient customer acceptance.

In our fixture and inspection tool design, we strictly adhere to the 3-2-1 positioning principle to restrict the six degrees of freedom of the product (3 planes + 2 edges + 1 point), ensuring positional consistency.

For precise positioning, we utilize locating pins, V-blocks, and profile-matching blocks , while pneumatic cylinders, lever clamps, and quick clamps are employed for secure fastening. Additionally, high-precision dial indicators are integrated to conduct accurate product inspections.

Key Features:
✔ Stable Positioning – 3-2-1 principle guarantees repeatable alignment.
✔ Efficient Clamping – Pneumatic and mechanical clamps ensure firm holding.
✔ Precision Measurement – Dial indicators verify critical dimensions with high accuracy.

Applications: Ideal for automotive parts, precision machining, and other high-repeatability manufacturing processes.

the manufacturing of fixtures and inspection tools, lightweight design is prioritized. The main structure utilizes aluminum alloy and anti-static engineering plastics , while high-strength steel inserts are applied to rigid contact surfaces . The aluminum alloy undergoes anodizing treatment , and polyurethane coating is applied to anti-scratch surfaces.

Additionally, fixtures and inspection tools must incorporate anti-asymmetry design , with modular positioning features for quick product changeovers, enhancing inspection efficiency and maintenance convenience.

For automotive part inspection tools , adjustable positioning mechanisms are adopted, which are calibrated using CMM (Coordinate Measuring Machines) . Moreover, 3D modeling and simulation analysis are performed on computers to verify the reliability of fixture design .

Key Requirements:
✔ Material Selection – Aluminum alloy (anodized) + anti-static plastics + steel inserts.
✔ Surface Treatment – Polyurethane coating for wear resistance.
✔ Modular & Adjustable Design – Ensures quick changeovers and adaptability.
✔ Verification – CMM calibration + 3D simulation for design validation.

This design approach ensures high precision, durability, and efficiency in production and inspection processes
