I. Chung mold company is specialized in manufacturing various specifications of different types of mold manufacturer. Second, the commonly used steel mold: 45 #, 40Cr, P20, 2738,2316,718, NAK80, S136, and so on. Companies generally use molds Shanghai Baosteel P20, 45 #. (Shanghai Baosteel P20, 45 # through our mold making process, not only can improve the life of the mold, can also increase the surface gloss of injection molds out of the product, but does not appear flash / flash.) Third, mold design Mold design is a pair of good qualified mold manufacturing premise of the company's technology department has 15 professional designers and product stylists mold structure, have more than 5 years of work experience, you can mold the whole structure and product structure analyzes (including: mold stripping slope, the epitome of the product surface, gating system design, the design of the exhaust system, cooling system design, etc.) repeated these molds are most likely out of the main issues will die structure design trials. Fourth, the company equipment Chung mold company has a full range of processing equipment, including eight CNC milling (in which a high-speed milling, precision can reach 0.1mm), 3 sets of spark can reach 0.1mm, 4 sets of carved (where a ramp degree carving), three large drilling machine, four wire cutting, a surface grinder can reach 0.02mm, a milling machine. Fifth, mold cooling system design of the cooling system design is a relatively cumbersome work, namely to consider the uniformity of the cooling effect and cooling, but also consider the cooling system to determine the location and size of the specific impact of the overall structure of the mold cooling system ; key positions such as moving or cooling mold inserts are; cool side slider and side cores; design and standard components to cool the cooling element of choice. Our company began in the mold design analysis of these series of questions, the way mold using recycled water to flow in every part of the mold, injection reduces cooldown time, improve production efficiency and greatly reduce production costs. Sixth, mold maintenance tool maintenance is more important than the mold maintenance, mold maintenance more the number, the shorter its life; rather die better maintained, its life will be longer. Three main points mold maintenance; 1. Routine maintenance of the mold: a variety of moving parts such as the thimble, the line position, guide post, guide sleeve refueling, cleaning the mold surface, sparse road transport water, which is a day when the mold production to be maintained. 2. Regular maintenance: regular maintenance other than routine maintenance should include cleaning exhaust ducts, charred bits plus trapped gas exhaust, damage, wear parts and other amendments. 3. Appearance Maintenance: Paint the outside of the mold base coating to prevent rust, while the lower die, scheduled to die dynamic model should be coated with anti-rust oil, should die to save closed tight, to prevent dust from entering the cavity. Seven, Chung mold has passed ISO9001: 2000 international quality system certification! Technical requirements are as follows: 1. Product molding process, the mold structure and production process analysis. Guarantee die life up to 1 million times. 2. Complete mold structure must be designed and machined parts and assembly requirements and the proposed injection process requirements. 3. Quality defects resulting in the appearance of plastic parts (such as shrinkage, etc.) or die structural problems (such as sub-surface setting, gate settings, die life and other issues can not be guaranteed). 4. Mold Appearance: Die appearance must ensure that no rust, no hit marks, no defects Qin modules defects. 5. Mold Transportation: Transportation must be installed on the mold clamping piece, packing strong, rust. 6. Mold Information: In the mold of delivery, we must provide a set of molds wearing parts and maintenance References
