South Korea and the current mold industry also learned through the website of the city related to planning, MASTER plastic rattan molding investment environment, such as the development of plastic rattan molding, which molds to create the city has a good role in promoting the brand. Another example is the establishment of corporate alliances, so that technology and products are highly complementary mold manufacturers together, to cooperate in the division of labor according to their characteristics, relying on leading enterprises to participate in market competition, to upgrade the industry level, from the current situation preliminary works well . plastic drawer mold  things are not to do their own thing, but is necessary for industrial development segment. Last year, the city's above-scale industrial enterprises mold more than 300 million yuan of industrial added value, and this year the new year, the city's mold industry has frequent success. Mold industry to do in a short period of six months, why can achieve such results? There is a saying called "right." Industry imperfect, you must do the industry to perfect it! Mold industry, too, conducting a thorough and meticulous investigation, research, after analysis, we found that the presence of "small, scattered, plastic mold manufacturer missing, unbalanced" and other major issues of the city mold industry. Under this situation, we seize the key, to break the bottleneck constraints. Mould Industry "Zoom" is the industry, it is merely serving the industrial development of an industrial economy. Our work includes specific exchange platform, the formation of alliances, improve the industrial chain base, strengthen plastic rattan molding industrial park construction, as well as a variety of ways, such as foreign investment. It should be said, plastic rattan molding industry has a very broad market prospects, great room for development. But the city's mold industry is just getting started, there are a lot of work to do. Said before just thinking, thinking right, the key is the next step in the concrete implementation and execution. No vacancy, no offside, industry do as a government department, for the development of the industry, according to market rules macro guidance, policy guidance, etc., and create a mechanism for sustainable development, specific market behavior by companies responsible.

plastic rattan garden furniture mold grim situation

In order to cope with the grim situation, the participants will jointly move the industry consensus: a, plastic rattan garden furniture mold Appropriately adjust product prices on the basis MASTER plastic rattan garden furniture mold of the original sales price up 10% to 15%; two, recommended the development of mold, putting other key products within the industry guide price; Third, improve corporate positioning, constantly seeking new ideas, new methods, such as the development of new products, increased non-standard products. Industry experts also pointed out that in the current situation, plastic rattan garden furniture mold standard Make plastic molds parts enterprises should pay more attention to product quality, product quality and only go up in order to sell a good price; have their own scale costs in order to set the sales price based on production capacity, price is dynamic, with the market and the changes in their capacity varies. In addition, to recognize the competitors plastic rattan garden furniture mold standard parts companies both on the market, plastic injection toy mould is also a partner jointly develop the market only learn from each other, in order to safeguard the long-term interests of the industry to achieve common development.

MASTER reaction injection moulding was first in the spring and Autumn period

Plaster mould was first in the spring and Autumn period, the ancestors with clay or stone carving out as a tool to coin money. Development up to now,the materials and processes are better than in MASTER injection molding supplies the past many advanced, in the material aspect, such as metal, resin, rubber, wood, plaster, several materials only gypsum is relatively easy to processing, no need of professional equipment, only need a knife or pieces of paper or wood, plus some soapy water as isolating agent can. Before making the plaster mold, people need to understand the properties of gypsum, gypsum powder is composed of a gypsum mine in quartz roasting by ground support, building materials stores a lot of big city in general can buy, their processing needs of small town of a class of area, is also the gypsum by grinding pestle, then roasted in a pot, burning fire, when the temperature to 800 degrees can be, but of course the quality no outside sell well. Nature when it comes to gypsum MASTER plastic container moldingpowder, chemically it is called semi  hydrated gypsum and burnt gypsum, it is mixed with water into a paste will soon after solidification, it is based on it by the flow of liquid into plasticity solid production molds and fire works, in the reaction process also generates heat. It should be noted, if too much moisture, will cause the solidified fastness variation condition, if need solid strength, should put the gypsum powder. Due to the condensation of solid gypsum can not be reused, so in the firing process must be fast, and be ready ahead of time and dosage of gypsum. Gypsum and gypsum products all have in common is absorbent, so people invented the slip casting method to make the blank, which is the removal of making plaster mold, another major use of gypsum.

MASTER plastic rattan garden furniture Forging die steel

Forging die steel. Generally speaking, there are two steel forging die more prominent role under the impact load when one is working. Therefore, the higher the mechanical properties of the steel requirements, especially for plastic deformation resistance and toughness demanding; Second, the larger cross-sectional dimensions MASTER china plastic injection molding  die (<400mm) so the steel hardenability requirements higher to ensure that the entire die uniform microstructure and properties. Common hammer forging steel floor there 5CrNiMo, 5CrMnMo, 5CrNiW, 5CrNiTi and 5CrMnMoSiV so on. Different types of hammer eye mode should be used in different materials. MASTER plastic drawer mold For large or large hammer forging die to 5CrNiMo as well. Can also be used 5CrNiTi, 5CrNiW or 5CrMnMoSi like. For small and medium forging die steel usually used 5CrMnMO.

Metal mold cavity surface thermal fatigue

Cavity surface metal thermal fatigue ( cracking ) . Hot mold work is characterized by intermittent . After each state of the metal forming the hot water to be cooled cavity surface oil, air and other media. Therefore . Hot mold working condition is repeated heating and cooling , so that the surface of the metal mold cavity to produce plastic container moldingthermal expansion and contraction , which repeatedly subjected to tensile and compressive stress . As a result, the cavity caused by surface cracks , called thermal fatigue phenomenon whereby hot die steel made for second basic performance requirements. That has a high thermal fatigue resistance . In general, the factors affecting the thermal fatigue resistance of steel are mainly : ① steel thermal conductivity. The high thermal conductivity of steel , a metal mold can reduce the degree of surface heating , thereby reducing the tendency of the steel to thermal fatigue . Thermalconductivity is generally believed that the amount of carbon steel and cooperation related to the high china plastic injection moldingthermal conductivity when the carbon content is low, it should not be hot die steel with high carbon steel. Commonly used in the production of carbon steel (C0.3% 5 ~ 0.6%) combined carbon content is too low. Causes decrease in the hardness and strength of steel .Isdisadvantageous.Critical point ② Steel. The critical point is usually steel (Acl) is higher. The lower steel thermal fatigue bias. Therefore . Usually by adding alloying elements Cr, W, Si, attracted improve the critical point of the steel. Thereby improving the thermal fatigue resistance of steel.
