Buyer questions

Quality Control FAQ

Answers stay within the catalog’s published dimensions, checking statement and packaging examples.

Discuss Your Requirement
01How are hinge dimensions checked?

The catalog describes tools developed to support checks during production. Published catalog dimensions or confirmed requirement dimensions can provide the relevant reference for the selected hinge family.

02Do you use product drawings during production?

Original catalog drawings organize reference symbols for the families where drawings are published. Confirm which drawing and dimensions apply to your selected product or requirement.

03How are custom dimensions communicated?

Send the required dimensions, technical drawing and a reference product or image. Add the application and quantity so the requirement can be reviewed and confirmed before production is discussed.

04Are different hinge types checked differently?

Different product families publish different size formats, structures and reference symbols. The applicable checking reference therefore depends on the named hinge family and confirmed requirement.

05Can I send my own technical drawing?

Yes. A drawing can communicate dimensions and the requested structure for discussion. The local RFQ preview can select a file, but it does not upload or send the file.

06How are products prepared before shipment?

The catalog lists standardized packaging and documents separate methods for the 20 Type and 12 / 14 / 16 Type series. Confirm the applicable packing requirement with the product family.
