What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

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

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

High precision plastic mold processing steps

High-precision plastic mold processing steps 1. Heating and pre-plasticizing:
Driven by the drive system, the screw conveys and compacts the material from the hopper. Under the combined action of the heater, screw and barrel outside the barrel, the material is gradually melted, and the material is gradually melted at the head of the barrel. The part has accumulated a certain amount of molten plastic machining. Under the pressure of the melt, the screw slowly retreats. The retreat distance depends on the amount required for one injection of the metering device to adjust. When the predetermined injection volume is reached, the screw stops rotating and retreats .


2. Mold clamping and locking:
The clamping mechanism pushes the mold plate and the movable mold part of the mold installed on the movable mold plate to close and lock the mold part on the movable mold plate to ensure that sufficient clamping force is provided to lock the mold during forming.
3. Move the injection device forward:
When the mold clamping is completed, the entire injection seat is pushed and moved forward, so that the nozzle of the injection machine and the main runner of the mold are completely fitted.
4. Injection and pressure maintaining:
After the clamping and nozzle are fully fitted to the mold, the injection hydraulic cylinder enters high-pressure oil, pushing the screw forward relative to the barrel, and injecting the melt accumulated in the head of the barrel into the cavity of the mold with sufficient pressure, which is caused by the decrease in temperature. To shrink the volume of the plastic machining china, in order to ensure the compactness, dimensional accuracy and mechanical properties of the plastic part, it is necessary to maintain a certain pressure on the melt in the mold cavity to supplement the material.
5. Pressure relief:
When the melt at the gate of the high-precision china cnc machining plastic mold freezes, the pressure can be relieved.
6. Retreat of the injection device:
Generally speaking, after the pressure relief is completed, the screw can rotate and retreat to complete the next feeding and pre-plasticizing process. (Under the general situation of existing injection molding, the movement of the injection seat to withdraw the main gate of the mold has been cancelled. (Perform this action when molding materials with serious salivation, such as PA).
7. Open the mold and eject the plastic parts
After the plastic part in the cavity of the high-precision plastic mold is cooled and shaped, the clamping mechanism opens the mold and pushes out the plastic part in the mold.
