What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Method of pouring and cleaning of castings

Commonly used pouring methods in investment casting are:
1) There are the following types of thermal gravity casting methods.
This is the most widely used form of casting, that is, after the shell is removed from the roaster, it is cast at high temperature. At this time, the metal cools slowly in the mold shell, and the mold can be filled with high fluidity, so the casting can well replicate the shape of the cavity and improve the accuracy of the casting. However, the slow cooling of the casting in the hot mold will cause coarse grains, which reduces the mechanical properties of the casting. When casting carbon steel castings, the surface of the casting that cools more slowly is also prone to oxidation and decarburization, which reduces the surface hardness, finish and dimensional accuracy of the casting.invest-casting.com Precision Investment Castings China prototype company service include : High Quality Investment Casting Parts Custom,Lost Wax Investment CastingSand Casting,Lost Foam Casting,Gravity Casting,Die Casting,Graphite Casting ,Casting Moldsmanufacturers.
2) Vacuum suction casting
Put the mold shell in the vacuum casting box, and suck the gas in the mold cavity through the tiny pores in the mold shell, so that the liquid metal can better fill the mold cavity, copy the shape of the mold cavity, improve the casting accuracy, prevent pores, pouring Insufficient defects. This law has been applied abroad.
3) Crystallization under pressure
Put the shell in the pressure tank for pouring. After the end, the pressure tank is closed immediately, and high-pressure air or inert gas is introduced into the tank to solidify the casting under pressure to increase the density of the casting. The maximum pressure abroad has reached 150atm.
4) Directional crystallization (directional solidification)
Some investment castings such as turbine blades, magnetic steel, etc., if their crystalline structure is columnar crystals arranged in a certain direction, their working performance can be greatly improved, so the directional crystallization technology of investment casting is rapidly developed.
Casting cleaning
The main contents of investment casting cleaning are as follows:
(1) Remove the mold shell from the casting;
(2) Remove the casting from the pouring system;
(3) Remove the shell refractory adhering to the casting;
(4) Cleaning after heat treatment of castings, such as descaling, edge and cutting gate residues, etc.invest-casting.com Metal Casting Material include : Stainless Steel CastingAluminum CastingIron CastingBrass CastingTitanium CastingSteel Casting

The task of investment casting process design is
(1) Analyze the manufacturability of the casting structure;
(2) Select a reasonable process plan, determine the relevant casting process parameters, and draw the casting diagram on the basis of the above;
(3) Design the pouring system and determine the module structure.
It should be noted here that when considering the above three aspects, the main basis is still the basic principles of the general casting process, especially when determining the process plan and process parameters (such as casting fillet, machining allowance, process ribs, etc.) , except that the specific data is slightly different due to the technological characteristics of investment casting, the design principle is exactly the same as that of sand casting.
The task and importance of investment casting process design
Investment casting is a casting process with less or no cutting. It was also called lost wax casting in the past. Because the castings produced by the investment casting process are better than other casting methods in terms of dimensional accuracy and surface quality In addition, the investment casting method can complete the production of some complex and difficult to process castings, so it is deeply loved by enterprises.
Regarding the investment casting process, the investment casting process design is one of the most important links in the entire investment casting process. This link has a large technical difficulty factor and plays a very important role in the entire investment casting process. This link is mostly due to some professional and technical people.
Like other casting process designs, the design tasks of the investment casting process are: a. According to specific requirements, analyze the craftsmanship of the casting structure; b. Plan a reasonable process plan, determine the relevant casting process parameters, and draw the casting diagram on this basis. ;c. Design the pouring system and determine the module structure. Except for the specific data due to the slightly different process characteristics of investment casting, the design principle is exactly the same as that of sand casting.
Since the investment casting process design link is of great significance to the entire casting process, and this link has very high requirements on the quality of the designers themselves, enterprises should pay considerable attention to this link.
