Q:How can the casting be free of trachoma?
3, the gate is not facing sand core, flush sand core, will cause trachoma.
Q:What's the cause of the choking of the casting?,
2. when casting mold exhaust condition is not good, in the casting material use consider whether and hinder its gas permeability; in the process to consider to release more pores, multi venting; core exhaust is particularly important.
Q:Casting pieces of plastic processing requirements can not fall off the skin,
The pre treatment temperature and the quality of plastic powder are likely to be problems
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q:Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
Q:Casting parts in rocker arm drilling, reaming, roughness, block.
Radial drilling machine can achieve boring, reaming function, but as much as you want, according to your requirements and material to determine!
Q:Is 316 casting better than 304 casting?
It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
Q:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:

Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
