Quality Control Standards

At ALLJACK we maintain a culture of quality.  Our project teams become actively involved beginning with the initial request for quotation and oversee the production process through its entirety.  Our engineers and designers approach every project, from a single prototype to the mass production of thousands of units, with an unparalleled level of professionalism and enthusiasm.  Every item that leaves our factory has been meticulously inspected and tested to ensure that it meets your precise measurements and requirements. In our industry, “a miss is as good as a mile”.  We leave absolutely no room for error.

A successful relationship is built on the foundation of customer communication.  We will carefully and accurately work to understand your product needs, ensuring that all of your specifications are met.  Products are inspected at each stage of the process, guaranteeing the absolute highest standards of quality.

Quality Control Procedure

Incoming Quality Control (IQC):

QC inspectors perform tests on samples of raw materials entering the warehouse.

In-Process Quality Control (IPQC):

QC inspectors periodically check semi-finished parts during production to ensure that they are made according to specification.

Outgoing Quality Control (OQC):

QC inspectors check each finished part to ensure that it meets all specifications and quality standards.

CNC Shop Quality Standards & Testing Equipment

At the CNC workshop, precision 2D and 3D measuring apparatus and various testing tools are applied to control the accuracy of part dimensions to ensure flawless quality. The ambient conditions of both the measuring center and CNC workshop are consistent: 20±2°C and 45±10% RH.

Standard Tolerance: ±0.005mm ~ ±0.1mm

Surface Treatment Quality Control Tests

color_inspection_lightThe Color Inspection Light is used to compare color differences for samples, using different light sources. It can simulate different environmental lighting conditions, ensuring that the color produced matches the color sample provided by the customer.


The Surface Hardness Tester is used to measure the hardness of metal materials and their resistance to deformation, scratches, and indentation.

Circulating Baths are used when the precise control of the temperature surrounding a sample is desired. These allow for samples to be tested at exact temperatures, and for the comparison of the effects that different temperatures will have on the sample.

The Coating Thickness Gauge is used to measure the thickness of the protective and decorative layers on the product surface (such as plating, lamination, and chemical conversion coating to name a few). This ensures that the layers have been applied properly and evenly.

The Cross Hatch Adhesion Tester is used to instantly measure the adhesion of a coating over a wide range of substrates. The coating film is cut into a lattice pattern and the coating adhesion is measured based upon how it delaminates from the substrate.

The Spectrophotometer is a tool used to measure the variation of color and reflectiveness under different wavelengths of light.

The Rubber Sclerometer is a tool used to determine the hardness levels of rubber products.

The Surface Roughness Tester is used to determine the surface roughness of a product.

The Gloss Meter is used to determine the level of gloss on the product surface by measuring light beams as they reflect off of the product surface at different angles.

The Abrasion Tester is used to determine the product’s abrasive resistance and can be applied to a wide variety of materials. This is used on products that will be subject to abrasive wear in service.

This tool uses pencils of a standard hardness to conduct scratch tests on the sample surface. The coating’s hardness is determined by which pencil grade scratches the coating.

The Push-Pull Scale is used for the testing of tension and compression.
