Mold Design: 

For sand casting, the mold is made of wood or other metal materials. In this process, we asked our engineers to make the mold size slightly larger than the finished product, and the difference is called the shrinkage allowance. The purpose of this is to melt the metal into the mold to ensure that the molten metal solidifies and shrinks, thereby preventing voids in the casting process.

Core Making: The core is formed by casting resin sand into a mold to form a casting of the inner surface. Therefore, the gap between the core and the mold eventually becomes a casting.

Casting Producing:  A mold is required during the smelting process. Molding typically involves the support frame of the mold, which is pulled out to separate during the casting process, where the previously placed core melts in the mold and then closes the die opening.

Cleaning & Machining:  The purpose of cleaning is to remove sand, sand and excess metal in the casting. Welding, sand removal can improve the appearance of the casting surface by burning the sand and the scale is removed to improve the appearance of the surface of the casting. Excess metal and other risers are removed. A step further by welding and grinding. Some castings are subject to special post-processing requirements such as heat treatment, shaping, anti-rust treatment, roughing, etc. Finally, Checking the defects and comprehensive quality finishing, before processing, and then re-processing, according to the requirements of different customers, we can do heat treatment, surface treatment, additional inspection and so on.

Control the size of the bright band of the part fracture to control the chip generation

Trimming clearance

Our company's original aluminum plate production experience is not rich. The cutting edge clearance is roughly the same as the steel plate, which is 8% of the material thickness. However, according to the soft characteristics of the aluminum plate, the 8% clearance makes the bright band of the fracture account for about 2/3. This produces some burrs, which are easily rubbed off during the flanging process. Form chips. We later consulted foreign standard parts manuals to optimize the trimming gap. The trimming gap is 10%-12% of the thickness of the sheet. According to this feature, the knife edge is trained. Ensure that all gaps are consistent. In order to avoid rubbing the fracture again after trimming. We make the cutting edge perpendicularity to -2°, and the cutting edge roughness reaches Ra0-20.4um.

Cutting edge

When timing the cutting edge, firstly ensure the consistency of the cutting edge of the trimming knife block to avoid parts cutting. Because the cutting is easy to produce aluminum strips at the same time, it can ensure that the parts are cut at the same time to reduce the cutting chips. The cutting depth is controlled to about 3mm, and the friction between the knife edge and the parts is reduced to reduce the generation of chips.

Edge shape

The cutting edge and trimming edge should not be too sharp. Use a file or whetstone to polish the cutting edge block and trimming edge so that the edge has a rounded corner of about 0.2mm to avoid the edge being too sharp. If not, the aluminum plate tends to be broken during the trimming process. Will produce a larger fracture zone.

Heat treatment of molds and inserts

According to reference foreign standard parts manual. The surface of the knife block is coated with a beryllium layer, which can improve the wear resistance of the knife block. Increasing the finish of the insert increases the hardness of the insert, which can avoid the generation of waste. Reduce mold maintenance.

For the OP10 drawing die, because it is a forming process, the material flows in the molding surface. It is inevitable that long-term work will cause the material to fall off and stick to the ratting tendons, which will also produce debris. For this problem, we applied electroplating to the mold. Increase the finish of the mold. It prevents debris from being rubbed, and also increases the hardness of the mold to prevent damage to the mold caused by napping.

For OP20/30/40 molds, we compare traditional electroplating and TD processing, and finally adopt PVD technology. Compared with electroplating, PvD has a higher degree of wear resistance. Compared with TD processing, the processing temperature of PVD is lower, about 240-350℃, which has a good control effect on the deformation of the insert.
