Plastic mold Quality Control
With HYX team’s strong executive capacity and enforcement power, HYX’s standard has become one of our hab.
HYX has made its own perfect production and management system. There are strict quality control managements in each process. We try our best to avoid mistakes, and put an end to extend mistake to the next process. Its ranges: from design analysis and inspection of plastic products to the research on design feasibility of Plastic Mold, from material purchasing to quality inspection of material, from processing technic selection and arrangement to quality inspection, from Plastic Moulds assembling and installation to Plastic Moulds test, etc.. For each process, there are homologous table and quality inspection standard. Each link should be ensured without defect, and then we can keep the delivered Plastic Moulds qualified.
Product design inspection:
Whatever product design made by HYX 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 Mouldsamendment, scrap and other unnecessary Plastic Molds 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 Molds 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 HYX 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 mold 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. HYX mold have planned to purchase more equipment to offer better service on QC work in 2009.
Plastic moulds testing’s acceptance check:
To some extent, our Plastic Moulds testing aims at finding the quality problems of Plastic Moulds, while not cover the problems. Thus, we have many steps in Plastic Moulds testing, including dry running, high pressure bearing, high speed injection and necessary long time Plastic Moulds injection inspection.
Plastic moulds delivery inspection:
In according to order documents, customer requirement and company standard, we will make strict inspection and acceptance check for Plastic Moulds. These related documents should be recorded and documented with other inspection report before delivery.

Processing Technic Department:
Technicians of processing technic department should audit modeling before Plastic Moulds production and make arrangements for Plastic Moulds tooling. It can ensure the Plastic Moulds being delivered successfully within shortest and rational delivery time. Also, it can avoid long production cycle and material waste problems that are caused by improper processing.
Staffs in proceeding department keep tracing the Plastic Moulds processing every day, collect schedule of each Plastic Moulds’s tooling steps by photos, and provide processing report for sales department. On the meantime, they coordinate with project director to monitor production processing and equipment modulation, and coordinate with each department to arrange Plastic Moulds machining. They handle the tooling delaying problems positively, and ensure the production department retrieves the time in the next step
Plastic Moulds Order Management
Project manager-sales people-quality and production form (catalogue pages)
1. Sales dept. contact directly with project dept. for all communication and technical information. We fully understand customer requirement and set up one complete record for customer history and record technical data.
2. Sale dept. and project dept .separately and clearly take each responsibility for one project, and devote all effort to achieve whole project.
3. Place high importance in delivery time and quality.
4. Every detail point can be tracked during order flowing. HYX mark each process by exact o’clock time and arrange every mission immediately the moment it released. For example, Steel material BOM list forwarded to purchase dept. at 16:15pm, 10th April, 2009. Material purchase effected at 17:05pm, 10 th, April,2009. So as to avoid any delay or even looking up any holding up of one project with knowing reason of the time difference of each step.
5. ISO/TS 16949 quality system to control quality, improve quality and management to avoid unreasonable expense of order running.
6. Every meeting between project dept. and production dept. arrange well the order running and improve the quality mentality, strong execution of HYX quality standard and mould tooling standard.
7. Good technical training for stuff in all fields, at the same time HYX HOLDINGS invest every year special fund for R&D dept engineers continuously technical invention and patent…
In order to improve order management continuously, HYX mold give regular technical training for sales department, project department, production department, and QC department. It aims at teaching each staff professional skills, so that everyone can monitor plastic moulds quality.
