Large Casting Series
The casting of the trampoline bed is made of sand casting. The initial strength of the sanding is high. The gray cast iron and the spheroidal graphite castings have less risers and no riser casting. The solid casting production adopts polystyrene foam molding, and the furan resin self-hardening sand is applied. modeling.

The casting of the trampoline bed is made of sand casting. The initial strength of the sanding is high. The gray cast iron and the spheroidal graphite castings have less risers and no riser casting. The solid casting production adopts polystyrene foam molding, and the furan resin self-hardening sand is applied. The shape is easy to operate, shortens the production cycle, improves the production efficiency, and is generally applicable to casting complex or thin-walled castings.
The high-strength cast iron HT250-300 is made of high-strength cast iron in the bed of the trampoline. It has strong tensile strength, reasonable manufacture, stable structure, high precision, wear resistance, long service life, simple production process and short production cycle. The structure of the casting of the trampoline bed is difficult to shrink and the shrinkage rate is reduced. The casting shrinkage of the material is different. The retractability of the retractable mold is good, the shrinkage of the casting is increased, and the casting of the trampoline bed is widely used in instrumentation and electronics. Processing of parts such as light industry, standard parts, bearing industry, auto parts industry, etc. It is especially suitable for non-ferrous metals.
