As the most important molding equipment in the production process, the quality of the injection mold directly affects the quality of the product. Moreover, since the mold occupies a large proportion in the production cost of the enterprise, its service life is directly related to the cost of injection molded products. Therefore, improving the quality of injection molds, maintaining and maintaining them well, and prolonging their service life are important management contents for  custom plastic injection profile  processing enterprises to reduce costs and increase efficiency. 1. First of all, you should equip each pair of molds with a resume card to record and count their use, care (lubrication, cleaning, rust prevention) and damage. You can find out which parts and components are damaged and the degree of wear and tear to provide discovery. And problem solving information, as well as the molding process parameters of the mold and the materials used in the product, in order...

PE corrugated pipe is made of high-density polyethylene as the main material, so it has the characteristics of light weight, corrosion resistance, good sealing performance, low friction coefficient, etc. PE corrugated pipes are most commonly used for underground cable protection and sewage Rainwater drainage pipes, etc., have very broad development prospects and application potential. The production process of PE bellows is co-extruded by the inner and outer extruders respectively, and it can be molded at one time. It is a plastic pipe with a very smooth inner wall, a corrugated shape on the outer wall, and a hollow layer between the inner and outer walls. Sealing rubber rings are embedded in both ends of the pipe, which has good waterproof and sealing properties. It can be laid on the sections with poor geology, and the construction is very convenient. At present, it is mainly used in communications, telecommunications, cables and other projects. PE corrugated pipe has a unique str...

Customized plastic products supplier  to share with you: In China's plastic machinery market, extruder as an important processing equipment, the development prospect is very optimistic. In the past two years, China's plastic extruder market has made considerable progress and breakthroughs, as shown in the following: the expansion of the emerging markets for extruders, the brand awareness has further expanded, the market competitiveness has further improved, and the proportion of exports to emerging countries It will also be greatly improved. Although China's extruder market is developing rapidly, the proportion of extruder exports is still low. The ever-increasing pressure on raw material costs and energy costs has made energy saving and material saving the focus of the extrusion processing industry. At the same time, extrusion technology suppliers can develop various energy-saving solutions from various perspectives to meet the energy-saving needs of users to the greate...

Three burnt ● Scorching phenomenon of  plastic extrusion pc cable conduit (1) The temperature reflects the extremely high temperature, or the temperature control instrument fails, causing the plastic to become extremely hot and scorched. (2) The glue outlet of the machine head has a large smoke, a strong pungent odor, and a crackling sound. (3) Granular scorch appears on the plastic surface. (4) There are continuous air holes at the glue joint. ● Causes of Scorch (1) Plastic scorch caused by ultra-high temperature control. (2) The screw has been used for a long time without cleaning, and the scorched material is accumulated and extruded with the plastic. (3) If the heating time is too long, the plastic deposits will be heated for a long time, which will cause the plastic to deteriorate and scorch. (4) The parking time is too long, and the machine head and screw are not cleaned, causing the plastic to scorch. (5) Change the mold or color several times, causing...
