Shanghai Matech Machinery Manufacture Corporation Ltd.is committed to the continuous improvement of thecastservice, become a society, customers, shareholders and employees long-term trust of the company. Our Company adhering to pirit of for the sake of customers, and win-win with customers , and through Matech Machinery Manufacture staff continuous innovation and development to provide first-class die casting use characteristics,Good after-sale die casting,Trustworthy die casting parts,die casting service attitude for enterprises , is what we have been working for. Details:Die-casting parts can be manufactured as die-casting auto parts, die-casting automobile engine fittings, die-casting air conditioning parts, die-casting gasoline engine cylinder heads, die-casting valve rocker arms, die-casting valve bearings, cast electric fittings, die-casting motor end caps, die-cast housings, Die-casting pump housings, die-casting construction parts, die-casting decorative parts, die-casting guardrail fittings, die-casting wheels, etc. With the continuous improvement of the development level of the domestic manufacturing equipment industry, the equipment level of the die-casting machine is also significantly improved, and the types of parts that can be manufactured are also improved. As we continue to expand, the precision of the parts that are die-cast and the complexity of the parts have also been greatly improved. I believe that in the near future, die-casting parts will better serve our production and life!The design of die-casting parts must take into account the wall thickness of die-casting parts, the casting fillet and demoulding slope of die-casting parts, the ribs, the minimum distance between the casting hole and the hole-to-edge of the die-casting part, the rectangular hole and groove on the die-casting part, die-casting There are seven aspects of the machining allowance of inserts and die castings in the parts. Casting fillet design specification: usually the parts of the die casting should have rounded corners (except at the parting surface), which can make the metal flow smoothly, the gas is easier to discharge, and the crack can be avoided due to the acute angle. For die-cast parts that require plating and finishing, the fillets can be evenly plated to prevent build-up of paint at sharp corners. The fillet radius R of the die-casting part is generally not less than 1 mm, and the minimum fillet radius is 0.5 mm.The design specification of the insert in the die-casting part: Firstly, the number of inserts on the die-casting part should not be too much; secondly, the connection between the insert and the die-casting part must be firm, and at the same time, it is required to groove, bulge, knurl, etc. on the insert; once again, the insert must avoid sharp corners to facilitate the placement and prevent stress concentration of the casting. If there is serious galvanic corrosion between the casting and the insert, the surface of the insert needs to be protected by plating. Finally, castings with inserts should be avoided. Heat treatment to avoid volume change caused by phase change of the two metals, so that the insert is loose.
