Mold making: We make three-dimensional modeling of products according to samples or drawings, and use this three-dimensional drawing to make aluminum or steel molds.

Wax injection: mix and stir liquid wax and solid wax into a paste wax paste, inject the wax paste into the metal mold with a wax injection gun, and take out the wax mold after cooling.

Wax parts combination: heat the stainless steel welding knife, and weld the wax mold on the gate rod according to the requirements of process design.

Stickling: Immerse the wax group into a cylinder containing water glass and other coatings, and apply the coating.

Sand leaching: quartz sand is applied to the wax group coated with paint, then immersed in a hardening tank containing ammonium chloride, magnesium chloride and other materials for hardening and drying, and then the operation of the next layer is carried out. This process is repeated for about 6 times and then completed.

Dewaxing: Place the wax group after the surface coating is hardened in the lost wax tank, and heat with steam to dissolve the wax and fall off, leaving the sand mold shell.

Molded shell baking: the mold shell is placed in the baking furnace to increase its strength.

Casting: the raw materials are put into a medium frequency electric furnace to melt, and the metal is added to make the material formula. the temperature of molten steel is raised to about 1600 degrees. after the chemical analysis before the furnace is qualified, the molten steel is poured into the mold shell through the casting ladle, the molten steel is filled into the cavity and then cooled, and the sample is taken for final inspection after the furnace.

Shell removal: the sand on the surface of the casting is removed by vibration.

Cutting: The casting is cut from the pouring rod with an oxygen-acetylene flame.

Grinding: Grind the riser with a grinder; grind the bad surface with a grinder.

Heat treatment: casting according to the requirements of the material for normalizing, annealing, quenching and tempering, induction hardening, carburizing, nitriding and other heat treatment.

Machining: according to the requirements of the drawings with CNC gold processing.

Final inspection: use tensile machine, impact testing machine, hardness machine and other testing equipment to test the mechanical properties of the test bar; use X-ray, ultrasonic, magnetic particle inspection and other testing equipment to carry out non-destructive testing on the sample; use three-coordinate standard, measuring tool and clamp gauge to carry out final dimensional inspection on the product.

Packing and delivery: after antirust treatment on the surface of qualified products, they shall be packed into glued-laminated wooden board boxes or iron leather boxes and shipped.

Focus on hot spots

Different classification of different casting molds

The casting mold mainly relies on the shooting head driven by the hydraulic cylinder to stamp the metal liquid into the cavity of the mold at high speed. Because the oil pressure is used, the whole pressure is relatively high, so it is called the casting mold process.

Automobile industry drives mold industry to grow gradually

In 2003, China's automobile mold is mainly a small number of mold team for the industry's landmark enterprises, today's automobile mold enterprises have developed to dozens of, a number of rapid rise of private enterprises have a considerable scale. Both technically and in terms of production capacity, these enterprises have greatly exceeded the iconic enterprises of the year.

Several aspects of the key process of precision mold processing

Grinding is the key process of precision mold processing. Finishing grinding should strictly control the occurrence of grinding deformation and grinding cracks, and even control the microcracks on the surface of the workpiece. The following aspects should be considered when formulating the precision grinding process.

Matters needing attention when cleaning die casting mold

After the die-casting mold is opened, how to clean the die-casting mold is always the most concerned problem from the production of products. Now for everyone to introduce about the cleaning of die-casting mold should pay attention to the matter.
