Qingdao Hilien Machinery Co., Ltd.

Here at HILIEN everyone knows how to take care about the products quality.

ISO-9001 standards were incorporated into our quality system to ensure the better quality products to our customers. According to the demands from our different customers we keep following below Quality Control procedures in our daily work.

Receiving Inspection

Raw materials must pass receiving inspection before they are released for production. In some cases raw material samples were sent to independent labs for special testing.

In Process Inspection

All phases of production are monitored by in-process inspections. A first-piece inspection is always conducted at each manufacturing stage. No production runs until this stage inspection is completed and the results found acceptable. For instance in machining workshop, each machine operator performs continuous inspection while producing the parts. Checking dimensions, observing the appearance and surface is required by the operator. The inspector should periodically audit samples of the product from each machine, taking samples at designated time intervals.

Final Inspection

All products technical details have to be final checked as per the drawings. The final inspection also includes surface treatment, appearance roughness, logo engraving or printing, packing details, shipping marks.

No order will be released until all shipping papers are stamped and signed by the final inspector. The goal of our quality control program is zero defects in 100 percent of all finished parts.

1. Don’t accept defective, strict inspection of supplier's raw materials.

2. Don’t manufacture defective, the production process is strictly controlled. For all products, the workers are strictly self-inspected on each machining process, and the quality inspectors do a regular inspection and spot inspection.

3. Don’t transferring defective, the defective products found in the previous process shall never be allowed to be transferred to the next process. Before shipment, the finished products shall be inspected again, and if any quality problems is found, and the products shall be reworked or rejected according to the relevant requirement.
