Working conditions to meet the requirements of the mold:
1,wear resistance 2,obdurability 3,Fatigue fracture performance
Specifications:
Mould have high production, good quality, low cost, save source of energy and material and so on .one mould steel use 3Cr17, quenched and tempered accurate to HRC30°±2°,an important part to special treatment.The mould made under the newest design,and the extrusion speed could increase 1.5 times.
Plastic mold design software:
PTC's EMX, Siemens's NX Mold Wizard, ClimatronE, Delcam Moldmaker, Missler's Topsolid Mold, Think3 of Mold Design, Manusoft of IMOLD, R&B's MoldWorks and so on.
Die structure:
Dies:Type embryo processed into shape profile.
Calibrator:Die extrusion of parison cooling shape
Tank:Enhanced cooling and forming the parison forming the product.
Die production process
1)ESI(Earlier Supplier Evolvement):This is mainly between customer and suppliers on product design and mold development in technical discussions, the main purpose is to allow suppliers to product designers clearly understand the design intent and precision, but also make the product mold designers to better understand the ability to produce products, process performance, and thus makes more rational design.
2)Quotation: Including the price of mold, mold life, working processes, machines and tooling required tonnage of delivery. (More detailed quotes should include the weight of the product size, mold size weight and other information.)
3)Purchase Order: Customer orders, and supplier deposit issued order accepted.
4)Production Planning and Schedule Arrangement: This phase requires the mold for a specific date of delivery to the customer to respond.
5)Design: May use the design software have Pro/Engineer,UG,Solidworks,AutoCAD,CATIA and so on.
6)Procurement of material
7)Machining: General processes involved in a car, gong(milling), heat treatment, grinding, CNC, EDM, wire cutting(WEDM), JIG GRINGING, laser engraving, polishing and so on.
8)Assembly
9)Trial Run
10)SER
11)SER Approval
Mold process to meet the performance requirements:
Mold manufacturing generally go through forging, cut machining, heat treatment, several processes. To ensure the quality of the mold manufacturing, lower production costs, the material should have good malleability, machinability, hardenability, and can be grinding of it; mould should also have a small oxidation, decarbonization sensitivity and hardening deformation cracking tendency.
1,malleability: have deformation resistance of hot forging with a lower , good plastic performance, forging temperature range, cold forging and crack mesh carbide precipitation and a low propensity.
2,Annealing technology: spheroidization annealing temperature range, low hardness and the fluctations in annealed small range, spheroidization rate is high.
3,machinability: Large cutting , low loss, low surface roughness.
4,Oxidation, decarburization sensitivity:when heated to high temperatures can be a good antioxidant, decarburization slow, not sensitive to the heating medium, resulting in pitting tendency of small.
5,hardenability: After quenching with a uniform and high surface hardness.
6,After quenching the hardened layer can be deeper, with ease of quenching medium can be hardened.
7,Quenching tendency of quenching distortion: Conventional quenching small volume change, shape warping, distortion slight tendency to lower abnormal deformation. Low sensitivity of conventional quench cracking on quenching temperature and the shape of the work piece is not sensitive.
8,grindability:Grinding wheel is relativiely small losses, no burn limits the amount of grinding large, the quality of the wheel and the cooling conditions are not sensitive, less prone to injuries mill grinding cracks.
