plastic rattan molding standards need to be improved

According to a comparative study of domestic and foreign steel mold found quality plastic rattan molding is mainly reflected in: pure, uniform, organize small, precise size. These aspects MASTER plastic rattan molding of the gap caused by cold die steel imports in the same strength steel lack of toughness, wear resistance is low; while hot work die steel high-temperature strength and thermal fatigue performance are low, so that made life than tool steel mold steel imports the die life significantly lower. the existence of many of the above plastic rattan molding quality problems, but are qualified by national standards of regular products. plastic rattan molding standard gap. Table 2 shows the chemical composition of plastic mold manufacturer the steel standards in different countries. Annealing North American Die Casting Association standards organizations assess detection can be found, banded structure, and impact toughness and other issues are not our country assessment indicators. This is the key question poor quality of domestic steel production. We must clearly recognize that in advanced countries of the enterprise, but the international standard as a minimum standard, thin wall injection molding  really carry out or perform is higher than the international standard of "enterprise standard" or "internal control standards", such as Sweden, plastic rattan molding there are very strict corporate standards. The reality is just the opposite with the current situation of China, is not conducive to the development of China's mold steel. To this end, the national standard plastic rattan molding should be closer to the international advanced standards as much as possible, as this will promote the improvement of the level of tool steel, tool steel is generally low quality change phenomenon.

plastic rattan garden furniture problems and the gap with international standards

plastic rattan garden furniture industry has entered a period of rapid development, which greatly promoted the production and application of technological advances in tool steel, MASTER plastic rattan garden furniture mold through the introduction of advanced equipment and technology, is capable of producing high-quality tool steel, the variety and quality of domestic steel mold has greater development and improvement. However, the overall level of speaking, plastic rattan garden furniture is still relatively backward, especially for the manufacture of plastic mold manufacturer high-grade steel mold, still in use imported steel, compared with the international advanced level, mainly in the following gaps: plastic rattan garden furniture varieties, specifications incomplete, more low-level, less high-grade. High-quality, high-performance tool steel varieties less. In terms of species, not yet formed plastic, glass, building materials, ceramics and other special mold steel series. Flat steels, modules, relatively low proportion of fine material products, utilization of steel about 10% lower than in other countries. To meet the manufacture of large, sophisticated, complex, requiring high life of the mold, the overseas development of pre-hardened steel, while the domestic steel basically stay in the annealing stage, or hot-rolled state delivery, and long lead times, which is China's home appliance industry the main reason a lot of die steel imports. plastic rattan garden furniture low degree of specialization. Quality steel, poor performance stability, poor visual quality. Chinese scattered in dozens of die steel production, most of the manufacturers of production technology and equipment is not complete, especially in the rear of the process, processing equipment behind, thereby constraining domestic steel mold improve improve quality and performance. plastic rattan garden furniture supply and marketing channels remain open. Mold manufacturing, mostly single or small batch production,plastic container molding  and varieties of steel required, specifications, a small number, the demand for timely delivery of industry characteristics, and mass production of metallurgical plant contradictory. May at any time resolve the problem of foreign retail stores through steel. China in recent years there have been some agents, steel shop and other intermediate sales cycle, but in the mold steel sales of service and level of foreign advanced level there is a gap, affecting the promotion and application of domestic steel mold. For example Bohler - Uddehum 100,000 users worldwide, mostly engineers, guiding users. It is noteworthy that matter, plastic rattan garden furniture of quality and service, from the gap between the needs of users is quite large, Plastic injection mold makers so we had a lot of "prefer a higher price abroad, do not want to buy a home at a low price" is not a normal phenomenon. Domestic and international prices of some steel mold is shown in table 1. From the table, than the domestic price of imported steel prices 3-6 times higher, reflecting the backwardness of China's mold steel from the price gap between the same grades.

Master injection moulder: injection molding machine injection molding machine

Master injection moulder: injection molding machine injection molding machine, injection molding machine or injection machine, a lot of factories that beer machine (PI Ji), injection molding products called beer pieces. It is the main forming equipment plastic products, thermoplastic or thermosetting material using plastic molding into various shapes. Injection molding machine injection device and a locking device according to the arrangement, can be divided into vertical, horizontal and vertical and horizontal composite.

注塑机是塑料加工业中使用量最大的加工机械，不仅有大量的产品可用注塑机直接生产，而且还是组成注拉吹工艺的关键设备。中国已成为世界塑机台件生产的第一大国，促进中国注塑机设备制造业发展的原因在于：（掌握注塑机）是与国际著名企业进行合资及技术合作；二是中国企业逐渐适应了机械零部件的国际釆购方式，掌握了釆购渠道。同时，我国注塑机的生产还呈现出很强的区域特色，浙江的宁波和广东的东莞等地，已成为我国乃至全球重要的注塑机生产基地。

The plastic injection machine is the processing machinery used in the greatest amount of plastic processing industry, not only have a direct production of injection molding machine products available large, key equipment and components injection stretch blow moulding. China has become the world's first big plastic pieces production, promote the development Chinese injection molding machine equipment manufacturing industry lies in: MASTER injection moulder is a joint venture and cooperation with the international famous enterprises; two is the Chinese enterprises gradually to the international procurement of machinery parts, master the procurement channels. At the same time, the injection molding machine production in China also shows a strong regional characteristics, Zhejiang, Ningbo and Guangdong and other places of Dongguan, has become China's most important production base of injection molding machine.

（掌握自定义注射成型）：注射系统是注塑机最主要的组成部分之一，一般有柱塞式、螺杆式、掌握自定义注射成型形式。目前应用最广泛的是螺杆式。其作用是，在注塑料机的一个循环中，能在规定的时间内将一定数量的塑料加热塑化后，在一定的压力和速度下，通过螺杆将熔融塑料注入模具型腔中。注射结束后，对注射到模腔中的熔料保持定型。

MASTER custom injection moulding: injection system is one of the most important part of injection molding machine, generally a plunger type, screw type, master custom injection molding form. At present, the most widely used is the screw type. It is, in a circular plastic injection machine, within a specified time will be a certain number of plastic heating plasticization, in certain pressure and velocity, the screw will melt plastic injection mold cavity. After the injection, the injection of the melt in the cavity to keep setting.
