What does the die EDM mean
EDM, an acronym for the English acronym, is often used in professional fields. If the whole name is Electrical Discharge, it means electric spark Machining That's called electroprocessing. It is mainly used for a variety of complex shape and small precision workpieces, such as the punch die, die, intensive, fixed plate, stripper plate, such as forming tool, template, use of electric spark machine-shaping metal electrodes, all kinds of micro hole trough, narrow gap, curve and so on, with a small machining allowance, high machining accuracy, short production cycle, low manufacturing cost advantages, has obtained widespread application in the production, the wire-cut edm machine at home and abroad has more than 60% of the total number of electric machine.
The injection molding round box is not satisfied with the molds.
Heat the mold with the temperature of the mould, then speed the injection a little faster, and then cool it when it is full.
What is the role of the guide in the mould
The "guide column" in the mould is also called "guide column".I hope my answer will help you
What mould steel can make injection mold?
25 crni3moal limitation is our country to develop a bottom nickel steel, by 880 ℃ quenching and 680-700 ℃ high temperature tempering, the hardness in HRC 20-25, machining, can be in the 520-540 ℃ ageing, hardness can reach 38-42 HRC, aging by coherent precipitate and matrix of ordered intermetallic compound, leicester and strengthened. Suitable for plastic mold with high precision 10 crni3mncual (PMS) is a kind of advanced mirror Ni - Cu - Al precipitation hardening plastic die steel, the electric arc furnace and electroslag remelting steel of legal system, material purity, have higher polishing performance, surface roughness after polishing can reach Ra0.05 0.12 ц m, etching performance and have good decorative pattern design, good cold and hot processing performance and mechanical performance, hardness can reach 38-45 HRC after aging, deformation rate below 0.05%, is a transparent thermoplastic parts and all kinds of special steel brightness requirements of plastic molding die
What is a mold bite
Is lousy skin grain, a lot of plastic parts surface is very thick leather grain, like a car instrument on the stage or storage battery mirrors, etc., fine grain with spark machine can play out, but do not to come out of coarse grain, you need to use chemical liquid will need mold cavity rotten into grain, also called texture
In die mold, is it better to use UG or PROE? That's a quick one. Is it convenient?
If it's a product design it's better to use proe. If you're doing mold design or programming I think it's better to use ug. The ug submodule, which is fast enough to unplug the electrodes, and the ug external technology is very mature, and the unplugged electrode is automated in the way out of the material. Mold design main push UG. There is a high degree of UG promotion. Software updates are fast, and someone might say that software updates are too late. Update quickly indicates that software companies have the money to be able to do so. It's good to learn a version, like 4.0. Although there were 5.0, most of the factory software was not updated, and computer hardware couldn't keep up. The UG mould library is full of information and is commonly used in the dragon card mould library.
What is the difference between the electric casting mould and the CNC working mould
Handmade mould and mould is a confirmed each metal mould plastic, metal parts, because the processing is more die steel, the requirements for machine tool, cutting tool hand is much higher than processing, processing cost is hand-board model. CNC programming is very different, CE, UG and so on, as long as master is able to be processed with the cutting tool, speed and feed.
The characteristics of cold making die steel
The hardness and abrasion resistance of cold steel mold is high Stamping die: Cr12MoV SKD11 DC53, etc
