A complete buying guide for die castings:

Die casting products are ubiquitous in our lives, involving all walks of life, if you have a need in this regard, then take a look at this article, this guide will introduce the relevant content of die casting in detail, I hope it will be useful for you help.

1. What is die casting

Die casting is an efficient and economical manufacturing process. It is used to produce geometrically complex metal parts formed by reusable molds. These molds generally have a long service life and can produce visually appealing parts. The die-casting process involves the use of a furnace, molten metal, a die-casting machine, and a mold customized for the part to be cast. The metal is melted in the furnace, and then the die-casting machine injects the metal into the mold.

Die casting is a kind of pressure casting part. The die casting machine pours metal such as copper, zinc, aluminum or aluminum alloy heated into liquid into the inlet of the die casting machine, and then is die-casted by the die casting machine to cast the restricted shape and shape of the mold. The size of copper, zinc, aluminum parts or aluminum alloy parts, such parts are usually called die castings.

Die castings have different names in different places, such as die casting parts, pressure castings, die castings, aluminum die castings, zinc die castings, copper die castings, copper die castings, zinc die castings, aluminum die castings, aluminum die castings, and aluminum die castings. Alloy castings, aluminum alloy die-casting parts, etc.

2、Benefits of die casting parts

(1) Because the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, they can be made into various shapes.
(2) The precision and finish of the product are very high, which greatly reduces the amount of machining of castings and the casting margin of metal copper, zinc, aluminum or aluminum alloy, and saves electricity, metal materials and labor costs.
(3)Copper, zinc, aluminum and aluminum alloys have excellent thermal conductivity, small specific gravity and high workability. The die-cast parts produced are of good quality and long service life.

3、Limitation of die casting parts

In the process of manufacturing die-casting parts, the control of the surface temperature of the die-casting mold has a very traditional Chinese medicine effect on the quality of the die-casting parts. Uneven or inappropriate mold temperature will cause the size of the die-casting parts to be different, and the casting will be deformed, resulting in thermal pressure, Defects such as sticking mold, surface depression, internal shrinkage cavity and hot bubble.

When the mold temperature differs greatly, the variables in the production cycle, such as filling time, cooling time, and spraying time, will have varying degrees of impact. Therefore, in the manufacturing process, special attention should be paid to the control of the surface temperature of the die-casting mold.

4、How die casting parts Works

The liquid metal is first filled into the cavity of the mold at a low or high speed, and the mold has a movable cavity surface. It is forged under pressure through the cooling process of liquid metal, which not only eliminates the shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains during forging, and the comprehensive mechanical properties of the blank are significantly improved.

5、Industries using die casting parts

Die-casting parts can be manufactured as die-casting auto parts, die-casting automobile engine pipe fittings, die-casting air-conditioning parts, die-casting gasoline engine cylinder heads, die-casting valve rocker arms, die-casting valve seats, casting power accessories, die-casting motor end covers, die-casting shells, and die-casting pumps Shells, die-casting construction accessories, die-casting decorative accessories, die-casting guardrail accessories, die-casting wheels and other parts.

Die-casting products have been widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, electric motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, architectural decoration and other industries.

6、How to Troubleshoot die casting parts

(1) Flow mark: The surface of the casting presents a smooth pattern of partial depression that is consistent with the flow direction of the molten metal and can be felt by hand.

Elimination measures: adjust the cross-sectional area or position of the inner gate, adjust the mold temperature, increase the overflow groove, adjust the filling speed appropriately to change the flow state of the molten metal filling cavity, and use thin and uniform coatings.

(2) Scratch: Along the demolding direction, because of the adhesion of the metal, the inclination of the mold manufacturing is too small, which will cause the scratch marks on the surface of the casting. In severe cases, it will become the scratched surface.

Elimination measures: correct the mold, ensure the manufacturing slope, polished indentation, rationally design the pouring system, avoid the metal flow against the core and wall, appropriately reduce the filling speed, modify the mold structure, polish the surface, and use thin and uniform coatings. Do not miss the spray paint and increase the iron content appropriately.

(3) Depression: The depressed part that appears on the smooth surface of the casting, the surface of which is in a natural cooling state.

Elimination measures: Improve the casting structure to make the wall thickness slightly uniform. The junctions with large thickness differences should gradually ease the transition, eliminate hot joints, select alloys with small shrinkage, correctly set up the gating system, and appropriately increase the cross-sectional area of the inner gate , Increase the injection force, appropriately adjust the thermal balance conditions of the mold, adopt temperature control devices and cooling, etc.

(4) Bubbles: Bubbles formed by gathering gas bulging under the surface of the casting.

Elimination measures: cooling the mold to working temperature, reducing the injection speed, avoiding vortex entrapment, choosing a paint with a small amount of gas, thin and uniform dosage, closing the mold after burning, cleaning and adding overflow grooves and exhaust ducts, adjusting the retention Mold time, trim smelting process.

(7) Crack: The alloy matrix on the casting is destroyed or broken to form a filamentary gap. There are two types of penetrating and non-penetrating, which have a development trend.

Elimination measures: Improve casting structure, reduce wall thickness difference, increase casting fillet, modify mold structure, increase mold working temperature, shorten mold opening and core pulling time, strictly control harmful impurities, adjust alloy composition, and comply with alloy melting specifications or renew Choose an alloy grade.

In addition to the above points, the common problems of die castings include cold water barriers, pores, under-casting, imprints, network burrs, colored spots, pockmarked surfaces, flashing, delamination, looseness, deformation, etc. Specific problems should be specific Analysis, here will not be introduced one by one. If there are some problems during use, you can consult relevant information or ask the manufacturer to solve them.
