Casting Die Design And Manufacturing

Many and many Metal components are used in many fields, that makes more and more metal process factories to be built. In these factories, machined metal parts and die casting parts are produced largely. So most of metal machined parts are suit for machinery industry and electric communication field. However, Metal die casting parts sometimes are needed at mass production, the bulk goods has to be formed by metal casting die & mold. But people should take a good consideration of the cost of casting die, compare to machined metal parts, that has additional cost. After balancing the earnings and costs, people will make up their mind that they will make a metal casting die to process casting parts in mass production. So metal casting die & mold manufacturing is certainly made before mass production. 

Design For Die Casting

Designing for die casting should ensure efficient production, good quality, and cost-effectiveness in die casting process. Since die casting process forces molten metal is injected into a mold (die), and solidify, cool and eject the shaped part from the mold. May involve several technical factors like material flow, cooling, and mold wear. Below are key points and considerations for designing for die casting. 

Casting Die Manufacturing 

Metal casting die & mold manufacturingis a complex and precise manufacturing process. It is executed by several steps, This requires specialized equipment, materials, and skilled-well technician. As one professional die casting manufacturer, we request making high precision die casting molds to produce premium quality die casting components. We also Summarized that some key steps and attentions when begining to manufacture die casting molds. 

1. Choose the Mold Material

Select high-grade tool steel or alloy steel for the mold to withstand high pressure, high temperature, and repeative wear from molten metal. Common materials include H13 steel,NAK80 steel for durability, thermal resistance and strong corrosion resistance.

2. Machining the Mold

Form the basic shape of the mold cavity using CNC milling or turning. Maybe Use EDM (Electrical Discharge Machining) or fine CNC machining for intricate features and detailed functionalities, such as detailed cavities and cores. Certainly Create channels for cooling, venting and overflow during casting.

3. Heat Treatment

Quenced the mold components to enhance hardness, wear resistance, and thermal stability. Meanwhile, You should control the die casting molds precision accuracy.

5. Polishing and Surface Finishing

Polish the mold cavity to achieve the required surface finish for casting part. Some molds maybe require having some texture and mirror effective on it. Commonly Apply surface treatments, such as nitriding or PVD coatings, to improve wear and corrosion resistance of the mold.

6. Assembly

Assemble the mold components, install the core, cavity, ejector pins, and guide pins on the mount of die casting machines. Test the fit and ensure proper alignment of the mold halves during die casting.

7. Test the Mold

Conduct a trial run on a die casting machine to test mold performance. Check for casting defects (e.g., porosity, misalignment), and make necessary adjustments until making a qualified first prototype and sample is conformed with industrial requirements. Metal casting die & mold manufacturing is over.
