The single purchase of raw material can’t exceed the regular output of each stove in aluminum alloy ingot company, confirmed the aluminum alloy ingot is a same batch when purchase in aluminum alloy ingot, they should supply laboratory sheet to follow aluminum ingot, we should keep it in the archive.
We will random inspection 30% of warehouse entry aluminum alloy ingots every time to do spectroscopic analysis, to confirm these two report are reached the standard, then to deposit.If these can’t reach the standard, return this batch aluminum alloy ingot. Before pouring, we do test stick and stove sample for spectroscopic analysis and Testing Mechanical Properties.

Technology department need to create the three-dimensional model according to customer’s drawing and feasibility of casting; Mold three-dimensional finished, after confirmed ,then make the toolings with CNC; For the first sample, we will inspect dimensions by Caliper or CMM, and do a size report. ; In the mass production, we will be according to 30% to do random check, and do size report; Use standard screw thread gauge to inspect screw thread.

No taper angle and burrs; Lines are smooth; Repair spilehole and defect on surface, if it can’t be repaired, it will be separated and scraped it.; There is no obvious repair vestige on product surface.

For the assemble product, we do Assemble quality inspection to confirm all the parts can assemble freely.
