Casting Process 1. Selection principle of pouring position 1) The important working surface or working surface of the casting should be downward. If it is difficult to achieve downward, it should be placed on the side as far as possible. 2) The large plane of the casting should be as far as possible. 3) Most…
DetailsSand Casting And Metal Casting Characteristics Sand casting has a wide range of applications and is suitable for almost all parts production. For some large, single or small batch castings, manual styling is the first choice. The machine shape can improve the molding speed and the dimensional accuracy and quality of the mold, and is…
DetailsAdvantages And Disadvantages Of Pressure Casting The advantages of pressure casting are as follows: 1) High productivity, can be die-casted 50 to 150 times per hour, up to 500 times, which is convenient for automated and semi-automatic production. 2) The casting has high dimensional accuracy and smooth surface (CT6～9, Ra0.4～3.2 μm). 3) The castings are…
DetailsLow Pressure Casting And Investment Casting The advantages of low pressure casting are as follows: 1) The pouring pressure and speed are easy to adjust, and can adapt to different mold types; the filling type is stable, the flushing force to the mold is small, and the gas is easy to be excluded. 2) It…
DetailsAdvantages And Disadvantages Of Centrifugal Casting Centrifugal casting is the main production method for cast iron pipes, cylinder liners, copper bushings and bimetal bearings. The maximum weight of castings can reach several tens of tons, and it can also produce heat-resistant steel roller and special steel seamless pipe blanks. Its advantages are as follows: 1)…
DetailsWhat Are The Design Elements Of The Mold? The structure of the blow molding, the casting mold and the thermoforming mold is relatively simple, and the structures of the compression molding die, the injection molding die and the transfer molding die are relatively complicated, and the parts constituting such a mold are also many. The…
DetailsWhat Are The Design Elements Of The Mold? Mold design and manufacturing are closely related to plastic processing. The success or failure of plastic processing depends to a large extent on the mold design effect and mold manufacturing quality, while the plastic mold design is based on the correct plastic product design. The structural elements…
DetailsThe Role Of Common Mold Base Parts (1) Fixed mold plate (panel): fix the front mold on the injection molding machine. (2) Flow channel plate (water plate): remove the waste handle when opening the mold, so that it automatically falls off (three plate mold). (3) Fixed mold fixing plate (A plate): the front part of…
DetailsHigh Expansion Polystyrene Molding Die The high expansion polystyrene molding die is a mold for molding a foam packaging material of various desired shapes using a raw material of expandable polystyrene (a bead composed of polystyrene and a foaming agent). The principle is that the polystyrene can be steam-formed in the mold, including simple manual…
DetailsMulti-Color Injection Molding Technology Features Multi-color injection, as its name implies, is a part that is molded with two or more plastics. The generalized multi-color injection molding includes over molding, which is realized by ordinary injection molding machine and two injection molding. The narrow multi-color injection molding refers to the injection molding of two or…
