Quality Control

Product design inspection:

Whatever product design made by  HONGMEI MOULD or offered by customers, we always make all round analysis and inspection, such as Plastic Mouldsing process feasibility, Plastic Moulds structure and movement feasibility, all the related plastic components matching situation, etc. It can avoid Plastic Moulds amendment, scrap and other unnecessary Plastic Moulds repair work, which are caused by product design fault. We believe that 10 more minutes we spend on the design, one month may be reduced in production.

Plastic moulds design inspection:

With precise analysis, foreseeing rationality analysis for Plastic Moulds design, best processing analysis and Plastic Moulds structure application, it offers the most professional solutions with the most suitable Plastic Moulds performance and technical specification as customer required. 

The inspection covers many aspects, such as Plastic Moulds intensity, mold-flow analysis, Plastic Moulds ejection, cooling system, rationality of guiding system, application of Plastic Moulds spare parts' specification, customers' machine selection and special requirement application, etc. All of these should be inspected in according with HONGMEI MOULD Plastic Moulds design standard. 

Steel purchasing inspection:

There is strict inspection process and time control of spare parts purchasing, the parts' standardization, size precision, hardness of Plastic Moulds material and material flaw detection and so on.

Processing quality control:

Control the size precisely, make self-inspection on each tooling spare parts in according to the requirements of drawing size and tolerance limits control. Only pass the inspection, can the spare parts delivered to the next working step. It is not allowed to make previous wrong work pieces inflow to the next tooling steps. For CNC milling, it needs strict auditing for procedures before tooling. After tooling, we will check up and control the precision by 3D coordinate measures. We have many measures: professional tooling technology training and machine maintenance; self-inspection of tooling workpiece and acceptance check made by quality department; rational work shifts system and tooling control system.

Quality inspection of plastic moulds installation:

Make complete inspection on Plastic Moulds to ensure the structure consistence and spare parts standardized. Project manager and QC people should all take part in Plastic Moulds inspection under the company standard, and make sure the product quality. If mistakes are found, they can be corrected promptly. It also can prevent mistakes. In addition, we will simultaneously do independent standardization test on Plastic Moulds cooling system, Plastic Moulds hydraulic oil channel system and hot runner system. 

Acceptance inspection on sample dimensions and plastic moulds size: 

QC department should make product inspection and submit the test report within 24hours after Plastic Moulds testing. Report should include full range test and analysis on product size, appearance, injection techniques and Physical Parameter. We use different inspection standard and tool for different products. In our labs, we do different test on high pressure injection, high speed injection, long time automatic running testing, and so on. QC department gives suggestions on the amendment and improvement for rejected product. We have accumulated abundant experience, which applies in Plastic Moulds production and offer good solutions for more and more customers. Along with our continuous improvement on equipments and measuring and test instruments, our product inspection tends to be more professional.
