I. Chung is a professional manufacturer of die different specifications of different models of turnover box mold manufacturer. 
 Second, plastic turnover box mold series 
 (Including plastic beer box mold, plastic tanks molds, plastic fruit crates mold, mold compartment, sorting box mold, plastic box mold, sealed box mold, etc.) 
 Die steel are commonly used: 45 #, 40Cr, P20, 2738,2316,718, NAK80, S136 and so on. 
 Turnover box mold is generally recommended to use 718, Shanghai Baosteel P20 material (because of 718, Shanghai Baosteel P20 mold through our production process can not only improve the life of the mold, but also can increase the injection mold out of the surface gloss of products, while not there will be flash / flash.) 
 Third, the mold design 
 Good mold design is a prerequisite for qualified mold manufacturing, the company's technology department has 15 professional mold Results 
 Stylists, designers and product structure, there are more than 5 years of work experience, you can mold the structure and analysis of all aspects of product structure (including: mold mold release slope, surface of microcosm of the design of gating system, exhaust system The design of the cooling system design, etc.) These are the most susceptible to mold the most important issue will die structure design for trial. 
 IV Equipment 
 Chung mold company has a full range of processing equipment, including 8 CNC milling (including a high-speed milling, precision can reach 0.1mm), 3 sets spark can reach 0.1mm, 4 sets carved (where a slope of carving) , 3 large drill press, 4 sets of line cutting, surface grinding up to a 0.02mm, a milling machine. 
 Fifth, the mold cooling system design 
 Cooling system design is a more cumbersome, namely to consider the cooling effect and cooling uniformity, but also consider the overall structure of the cooling system of the mold cooling system to determine the exact location and size; key positions such as the dynamic model or cooling inserts; side of the slider and the side core cooling; cooling component design and selection of standard components cool. Our company started in the mold design analysis of these series of issues, tooling use of recycled water in the way in every part of the mold flow, reducing the cooling time of injection time, improve production efficiency and greatly reduce production costs. 
 VI, mold maintenance 
 Mold repair and maintenance is more important than the mold, the more the number of mold maintenance, the shorter its life; and tool maintenance, the better, its life will be longer. Three main points mold maintenance; 1. Mold maintenance: various moving parts, such as thimble, the line position, guide post, guide sleeve refueling, 
 Mold surface cleaning, carrying water of the sparse channel, which is mold to maintain every day. 2. Regular maintenance: Regular maintenance, including routine maintenance and also pay to clean up the exhaust slot, trapped exhaust gas burning black level increases, damage, wear and tear parts of correction. 3. Appearance and maintenance: Die embryo outside the paint coating to prevent rust, the next mold, scheduled to die dynamic model should be coated with anti-rust oil, mold should be kept tightly closed to prevent dust from entering the cavity. 
 VII, Chung mold has passed ISO9001: 2000 international quality system certification! Technical requirements are as follows: 
 1. Product molding process, mold structure and production process analysis. To ensure that the die life of up to 100 million times. 
 2. Must be designed to complete the mold structure and processing parts and made assembly requirements and injection process requirements. 
 3. Quality defects caused by the appearance of plastic parts (such as shrinkage, etc.) or die structural problems (such as sub-surface setting, gate settings, die life can not guarantee and other issues.) 
 4. The appearance of mold: mold appearance must ensure that no rust, no hit marks, no defects and other modules handling defects. 
 5. Die Transport: Transport must be installed on the mold clamping piece, packing strong, rust-proof. 
 6. Die: In the mold of delivery, we must provide a set of wearing parts and maintenance mold reference.
