Molding of Dongguan Precision Casting Processed Castings
Dongguan precision casting production and processing casting moulding design
Casting is one of the basic professional skills of modern machinery and equipment manufacturing industry. As a kind of metal material heat treatment expertise, the casting of machinery and equipment castings has gradually become old-fashioned in China.
1. Classification
Foundry machinery and equipment are generally classified according to their appearance, and are habitually divided into general sand casting and special casting. General sand casting includes three types: green sand casting, dry sand casting, and organic chemical hard-bottomed sand casting. According to different appearance materials, special casting can be divided into two categories: one type uses pure natural mineral resources sand as the main appearance material, such as investment casting, shell casting, air pressure casting, clay casting, solid casting, Porcelain mold casting, etc.; one type uses metal materials as the main mold material, such as metal material mold casting, suction casting, continuous casting, working pressure casting, bottom pressure casting, etc.
The casting post-treatment process carries out quenching and tempering treatment, plastic and beauty treatment, anti-rust treatment solution and preliminary processing to the finished castings. The post-treatment process of castings is the last process in the production of casting equipment.
Casting finishing is the process of removing the casting from the mold, removing the remaining part other than itself, and polishing the surface of the cast-rolling casting equipment. The main work is to clean the core and core iron.
Dongguan Precision Casting Non-Ferrous Aluminum Alloy The non-ferrous aluminum alloy used for pouring castings is a type of casting equipment. Mainly include cast alloy copper, cast aluminum alloy profiles, and cast die-cast aluminum.
The appearance of simulated castings composes the processing technology configuration or consumable parts of the casting cavity. In order to ensure that the composition meets the requirements of the die, the face should have satisfactory compressive strength and bending rigidity.
The riser is an additional part of the compensation on the upper or peripheral surface of the casting equipment to prevent the casting from showing defects. In the casting mold, the concave mold of the riser is a vessel for storing shape memory alloy.
The core box uses the core sand as a molding core processing technology casting equipment. It can be made of wood, plastic, metal or other materials.
