Quality Control
QUALITY CONTROL
3A Prototype invests a huge amount of money to inspection equipment and inspectors training. We have set up a quality control system and ensure every part is inspected and approved to release by inspection department prior to shipment. The basic goal of our quality control is to ensure our products and service can meet specific requirements from customers and ensure our production can be dependable, satisfactory and consistent.
Our Major Inspection Equipment
Inspection Tool Name | Function | Specification |
---|---|---|
CMM (660LBS and CROMA-C) | Geometry and size check | It mainly refers to an instrument for measuring through three-dimensional point taking. Can be utomatic measurement, suitable for batch production |
2D measurement explorer (VIEMAX C4.3.2 and VMS-3020) | Multiple data measurement | It is a high-precision and high-efficiency precision measuring instrument integrating software, light, machinery and electricity. Can be utomatic measurement, suitable for batch production |
Height gauge | Height measurement | Its main purpose is to measure the height of the workpiece. In addition, it is often used to measure the shape and position tolerance dimensions. |
Internal micrometer (12mm to 100mm internal holes) (Mitutoyo) | Internal holes | Precision measurement of internal dimension |
Optical microscope | By magnifying the specific shape of the object, studying the sizes and shape | Very tiny holes and burrs, scratch, material inside bubbles etc |
Hardness | Rubber, plastic hardness test | |
Digital Calipers | Geometry and size check | The reading is intuitive, easy to use and has various functions |
Pin gauge | Internal holes check | Can be 1 to 10mm small holes, tolerance can be 0.001mm |
Thread gauge | Thread check | |
Plug gauge | Gap check | It is mainly used to check the gap between the two joint surfaces |
Edge to hole center caliper | Edge to hole distance check | |
Other inspection tools/equipment | Check with us if you want to know our other inspection tools and equipment |
How Does 3A Prototype Do the Quality Control?
We will do the FA inspection and rolling inspection, for high volume production, we do CPK analysis.
Detail Inspection include:
Dimension Inspection
Parts critical dimensions will be checked according to 2D or customers special tolerance or our standard ISO2768 tolerance
Visual Check
We will check the surfaces to see if any defect on the surface and also compare the parts to 3D file to see if any feature is missing.
Small Features Check
We will use microscope to check internal very small features and burrs.
Color Match check
Parts color will be checked according to customer's sample, RAL or Pantone book.
Threads and Holes test
We have a few sets of threads and pin gauges to test the holes and threads. Our pin gauge tolerance can be +/-0.001mm.
