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

How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

Introduction to the method of aluminum alloy die casting to solve casting porosity

Method to solve casting porosity

First analyze the reasons for the formation of stomata, and then take corresponding measures.

  • (1) Choose dry and clean alloy materials.
  • (2) Do not overheat or degas the melt under control.
  • (3) Reasonably choose the die casting process parameters, especially the injection speed. The starting point for speed-regulating high-speed machining.
  • (4) Sequential filling helps to discharge the cavity gas. Pouring I: 1, and the runner has sufficient length. It should be 50 ram, which is conducive to the smooth flow of alloy liquid and gas discharge.The thickness and direction of I:1 can be changed, and overflow grooves and exhaust grooves are set at the holes. The sum of the cross-sectional area of ​​the overflow product is not less than 60% of the sum of the cross-sectional area of ​​the gate part, otherwise the slag discharge effect will be poor.
  • (5) Choose good performance paint and spray volume control.

Choose the right die casting machine

Die-casting machine is the key equipment for die-casting production, and its performance objectively determines the quality of die-casting parts. The correct choice of die-casting machine is essential to ensure product quality, improve production efficiency and reduce production costs. The performance of the die casting machine depends on two aspects.

Sufficient clamping force: to prevent the flow pressure of the molten metal from reaching high peaks, and to prevent flashing and flying materials.

Sufficient injection capacity: to ensure that the stand casting process will not cause overheating or a large amount of overflow of the mold, and at the same time ensure that the machine has enough capacity to transport enough molten metal and fill the cavity as required to accelerate the speed in a short time.

Design of Die Casting Mould Runner

Because the zinc alloy must fill the cavity in a short time, the design and manufacturing of the die-casting mold and its runner system are much higher than that of the plastic mold.

The runner system guides the metal solution to fill the cavity in some way. It plays an important role in the flow direction of the metal liquid, pressure transmission, filling time, exhaust conditions and mold temperature distribution.

It is also an important factor that determines the quality of die castings.
