Auto parts water glass casting

Natural quartz sand, thermoplastic urea-formaldehyde resins, urotox products and synergists are the key choices for laminated sand. Appropriate adjustments in curing rate, de-filming, circulation, collapse, casting surface finish, storage, etc. are made according to the different technical needs of the user. Vehicles, tractors, hydraulic parts, etc. that provide one of the affordable molding materials.

Raw sand raw and auxiliary materials

1. Raw sand is the main body of hinge laminated sand casting, its high refractoriness, less volatiles, the particles themselves are high strength. Natural silica sand is generally used, which is cheap and can meet the forging regulations. Special sand is only used for castings with special requirements: such as zircon sand, chromite, vitriol, hematite and other raw sand as cladding sand

2. binder: thermoplastic phenolic resin is widely used as a binder, the

3. curing agent. Lubricating fluid. Additives: Uroto products are conventional curing agents for laminated sand. 5%-20% of the resin is added.

4. As the laminated sand process is perfect, the direction of development is based on the pre-rule. Low-cost products. And the impact on the environment and sand system is not large, the next five years the amount of cladding sand will have a certain increase. Low pollution and recycling of spherical clad sand casting will continue to put forward higher requirements, while with the growing awareness of environmental protection.
