What Problems Should Be Paid Attention To In Outsourcing Production And Proce...

1. The first thing to do is to carry out on-site inspections, verifications, and evaluations of the verification management system for the outsourcing production and processing enterprises, and make a work summary.

(1) Injection molding outsourcing production and processing companies need to use a qualified 5s office environment to see if it meets the standard of production safety.

(2) Whether the injection molding outsourcing production and processing enterprise has the conditional quality ideology, core concept of life, whether the quality is the first customer responsible, and confirm whether its work responsibility is serious.

(3) Whether the precision of the machinery and equipment of outsourcing production and processing of injection molding and whether its production capacity, management level, deep processing capacity and level meet the standard production standards. At the same time, confirm the quality of production and processing and the delivery period.

2. Draw up a scientific and reasonable outsourcing list, and carry out production and processing based on the standard of parts and components. Avoid oral standards as much as possible. The drawings produced and processed outside the standard are in accordance with the standards, and the drawings produced are cost-effective.

3. After receiving the products made by the outsourcing processing plant, large mold enterprises must have special personnel to carry out quality inspection and acceptance of the products, establish the acceptance standards for outsourcing production and processing, and try to avoid the inspection methods recognized by the mold team leader, which can effectively ensure The outsourcing quality of molds helps to improve the quality of outsourcing production and processing products.

4. For the outsourcing production and processing of plastic molds, special attention should be paid to the surface roughness of the processed parts.

(1) The dimensional accuracy of the cavity and the movable mold is confirmed by the CNC milling machine, and the tool marks on the parting surface and the cavity surface are recognized as meeting the standard.

(2) Pay special attention to the surface roughness of the wire cutting parts. If the surface roughness of the inclined ejector rod is like a sawed surface, the size after correction will not reach the standard.

(3) After EDM, prevent "white layer" on the surface of the production process. This phenomenon will seriously affect the appearance of the product, and it will also increase the difficulty of subsequent polishing operations, causing cracks on the mold surface and premature failure.

The reason for this phenomenon is mostly due to the incorrect selection of the machining process rules during EDM. Another reason is that the long-term use of the working fluid and the deterioration and heavier of the working fluid make the surface quality of the processed surface not up to the standard.

(4) The production and processing of deep hole drills should pay special attention to the roughness, dimensional accuracy of the inner hole of the ejector pin, the size and position of the cooling water hole and its depth, etc.
