The usual practice of injection mold processing and maintenance is to wait for the mold to cool, then clean the mold (because the surface of the injection mold is acidic, it is easy to spray the rust inhibitor into the mold to corrode the outside), then spray the rust inhibitor and close the mold. Remove the mold from the plastic machine for storage, and there is no need to clean the mold before the next normal injection, so as to avoid the increase in production costs due to the large amount of mold cleaning agent. The end user’s intention is that as long as the mold temperature is very low, the anti-rust oil on the mold can be taken away when the first product is manufactured, and the back of the product surface will not stick to the residual anti-rust agent on the mold, thereby avoiding A lot of waste.
The wax transparent injection rust inhibitor spray quickly forms a dense semi-dry protective soft film, which integrates the five functions of anti-corrosion, rust prevention, dehumidification, lubrication and penetration; super permeability and adsorption can be on the surface of the mold and various metal surfaces The formation of a unique moisture replacement component can effectively prevent the corrosion of the metal surface from various unfavorable factors. Long-term comprehensive anti-corrosion and anti-rust of the mould. It is suitable for the production and storage of plastic molds and the rust of die-casting molds, as well as the rust of other metal tools and parts.
Rust inhibitors are divided into waxy rust inhibitors and oily rust inhibitors. Let’s compare first: The disadvantages of oily transparent mold rust inhibitors are that they are basically not dry when sprayed, and the oil is unstable. After erasing, local rust spots will occur, and some products are still It will flow and the anti-rust period is short.
1: Micro molds require much higher processing equipment than traditional injection molding. The processing of micro molds generally has two trends: one is to use mirror spark processing to ensure high precision; the other is to use graphite electrodes for EDM, because The wear of graphite electrodes is much smaller than that of copper electrodes. Two commonly used comparison processing methods are to choose electroforming molds. Choosing electroforming technology can ensure high accuracy, but the defect is that the processing cycle is long, each hole must be processed separately, and if there is a small damage in the production, it cannot be To correct, the damaged chakra can only be replaced from the beginning.
2: Since the micro-mechanical mold is a milligram-quality finished product, if an ordinary pouring system is used for injection molding, even after optimization and improvement, the mass ratio of the final product to the material in the casting system is still 1:10.
Mold temperature is also a very important parameter for micro injection molding. Facing the high-quality needs of customers, the most commonly used method is to borrow the concept of high-gloss injection molding and enter the rapid heating and cooling system.
