FAQ
- Make cell phone lens what mould material is best! ?
- Use the S136 vacuum to make sure you're talking. Besides the quality of the material, the polishing process is also very heavy, the material will be burned with orange peel
- 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
- How to calculate the cost of plastic mould?
- Mold calculation cost is actually very simple, mold steel and toll fee counting and personnel salary, these are the main three cost, mould quotation I do work more than ten years, the products are numerous, I have a look at any plastic products will be able to know the price, if I can help you have drawings or samples
- What is the difference between a large water inlet and a thin nozzle?

Simply say: the big water mouth is two plate molds, the small water mouth is three plank model, two is only the difference one scraper board. The thin water mouth is: more than a big water mouth to push a board. 9, the sex limited gate (gate) : advantage: fast filling, pressure is small, feeding capability is strong, suitable for high viscosity, illiquid plastic, less pressure loss. Disadvantages: sealing water the long, slow cycles, internal stress, Influence on the plastic parts is big, difficult to remove. Restrictive gate (gate) : advantage: shear, friction, viscosity, easy filling, texture clear fast cycle efficiency, reduce internal stress, prevent deformation, less influence on product
- Because many of the molds in our factory have batch sewing, who can tell me how to fix the batch seam. Because I don't understand, but I'm going to learn, so I want to know in advance, thank you very much!
- Batch of feng there are a lot of ways, such as plunger batch of feng can increase plunger diameter or welding, we can reduce the parting surface batch of front face or weld FIT mould again. You do a year or two will find a lot of ways

- In order to read this major, do I think you should think about yourself before you want to work in the mold industry? Working after graduation is a difficult question to choose
- What is the role of the grooves in the guide column
- Storage of lubricating oil and cutting groove action. Because of the relative motion of the guide when the guide is working, because the clearance is small, the oil can be scraped off for a long time. So the design of this groove allows the lubricant to stay on the length of the guide column, not all of it to the end. Because the processing accuracy is different on both sides of the guide. Level 2 orientation precision, for example, sliding guide part of guide pillar and guide bush of requirement is H7 / h6, guide pillar of the fixed part and the mold base with the mounting holes is H7 / s6, relief groove guide pin can be divided into two sections, one section for h6, another for s6, so relief groove is a must have!
- What does the mold and the flying model mean
- That's the model, Hong Kong. The British side to FIT.I hope my answer will help you
