Machined Mold Plate CNC Pocket Rough Machining Cavity and Core Boards

Mold plates

Now there are also some customers who do not order a single complete set of mold base, but only several mold plates. After receiving them, customers process and assemble them by themselves. This method can save a lot of time and shorten product delivery time.

Rough processing

Process the rough shape. After roughening, there needs to be some margin left for subsequent precision machining.

Cavity and core plates

The parallelism and verticality of pocket should be controlled within 0.02mm. The length, width, and depth tolerance of the precision mould base should be 0~+0.02mm, and the thickness tolerance of the main plates should be ± 0.02mm. Precision machining is required for screw holes, water line holes, ejector pin holes, nozzle holes, etc. All surfaces should be scratch free, bright and flat, all chamfers should comply with our company's standards and should be uniform. In the actual machining process, corresponding precision requirements will be formulated based on specific mold design and customer needs.

Aperture and spacing of cavities are important parts. The dimensional tolerance of the aperture is within a small range to ensure precise fit with the mating parts. The surface of the aperture is smooth, without scratches, burrs and other defects, which can reduce friction and wear, and improve the life of mold. In a multi cavity mould base, the hole spacing at the same position should be consistent, that is, the hole spacing between each cavity should be equal, which helps to ensure the uniformity and stability of all parts of the mold. After processing, we conduct strict CMM testing on the hole spacing.
