Precision Hot Runner Plastic Injection Multi-Cavity Mould Base P20 4Cr13H

Accessories

All accessories of mould base can be provided according to the drawings. We can provide standard and nonstandard accessories such as HASCO, MISUMI, PUNCH, DME and LKM. Also, we process special accessories including bronze accessories, ball cage bush, self-lubricating parts, etc.

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.

Runner plate

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.

Testing

We use CMM coordinate measurement and generate accurate measurement reports. Its high-precision measurement results can ensure product quality and tolerance requirements.

Anti-corrosion treatment

In order to reduce the impact of rust on mould base during shipping, we will use anti rust spray and anti rust oil on the surface of mould base, and then wrap them with plastic film. If necessary, vacuum packaging will be used.
