Auto Parts Precision Casting Product

Are main productsof our company adopted complex process (silica sol + water glass), adopt the low temperaturewax, four shell layer using silica sol process, three layer using water glassprocess, composite process to produce a product that no matter from the surfacefinish, and internal quality and silicon sol process almost the same, the priceis cheaper than silicon sol process a lot, and water glass price though it's cheap,but the product is very rough, and composite technology products of goodquality and low prices, the most suitable for large batch of products, canguarantee the quality of customer requirements, and can guarantee a reasonableprofit space, so, Our foreign customers have been cooperating with us for 8years, and we have cooperated very well. List the approximate prices ofdifferent processes in China today: silicon sol precision castingproducts cost $5.3-$6 /KG Precision casting products withcomposite process cost $2.50 - $3.3 /KG The precision casting productsof water glass process cost $2.1 - $2.5 /KG   Inspection: ourcompany has special physical and chemical laboratory, with perfect inspectionequipment (spectrometer, three coordinate measuring machine, metallographicanalyzer, impact test machine, tensile testing machine, hardness tester,magnetic particle inspection machine, ultrasonic testing, etc.), can satisfythe customer different product requirements
