The Quality, Environment, and Occupational Health and Safety management system certifications are internationally recognized standards. From November 12 to 15, 2025, SGS conducted a surveillance audit for Gree Daikin Precision Mold Co., Ltd. (hereinafter referred to as GDM) on its ISO 9001 Quality, Read More

Detailed Explanation of Technical Features for Pre-coated Metal (PCM) Dies:Material Selection: Use of high-hardness, high-wear-resistance materials (e.g., powder steel, carbide) to resist abrasion and maintain long-term smoothness.Structural Design: Incorporation of large radii, optimized clearances Read More

The core 6 is removable. During operation, the workpiece is sleeved onto the core and placed inside the threaded sleeve 15. When the press slide descends, the punch 9 first presses down on the core 6, causing the workpiece to descend together with it. Then, the limit pin 11 presses down, and the slide block 14 descends along with it. The external profile of the slide block 14 is straight-threaded; during design, care must be taken to ensure that the inclination angle of the slide block is not too large, otherwise the die is prone to jamming. See Figure 2. Read More

Stamping is a common workshop production method that enables the manufacture of metal workpieces with high complexity. During the stamping process, factors such as stamping depth, die material, and design can lead to occurrences of warping and twisting, which affect the quality of the stamped parts Read More

When determining their placement, flexible adjustments must be made to ensure there is no interference with ejector pins, ejector sleeves, angle lifters, support pillars, spring-loaded rods, or ejector plate guide pillars. Read More

The copper tubes in air conditioners' condensers and evaporators pass through tube sheets, which provide support. These sheets contain numerous holes arranged in orderly patterns. Even with the same external dimensions, products can vary significantly due to different hole spacing layouts, resulting in numerous product models. This diversity requires mold changes to produce different styles. Read More

During the production adjustment process of injection molds, the mold temperature is often increased to facilitate adjustment and improve the appearance of the product. However, many molds are not matched to simulate production conditions during the mold matching process, resulting in the mold inser Read More

The pressure exerted by the top of the plunger/screw on the plastic serves to overcome the resistance of the plastic flowing from the barrel to the cavity, to provide the filling rate of the melt, and to compact the melt. Read More

Traditional stamping die processing involves four main processes: shearing, punching/cutting, bending, and welding. With the advancement of science and technology, the four major sheet metal processing processes have evolved to include laser cutting, punching, bending, and welding. Read More
