Investment Casting

 

Investment casting known as lost wax casting is a precision metal casting process as it is capable of making high accuracy and intricately detailed castings compared to similar manufacturing processes such as sand casting.Materials involve carbon steel, low alloy steel and stainless steel and typical part weighs from 0.05-100kg.

The main process of investment casting as follows: Pouring simulation to verify the manufacturability,
Mold development, Wax pattern, Shell preparation, Metal pouring, Cleaning,Sand blasting,Heat Treatment, each process will do inspect and also have final inspection as whole before shipment.

Densen Group provides high-quality investment casting services for a variety of industries such as Medical Equipment,Pump & Valve Industry, Articulated Steel Structure, Food Processing Industry, Earth Moving, Railway, General Engineering and Steel Plant etc.The investment casting process allows for very precise metal features that can produce parts
with smooth surfaces such as Ra1.0.This process can create near-net-shape parts with outstanding dimensional accuracy.

Silica sol investment casting and Water glass investment casting are the two primary investment casting methods nowadays. The main differences are the surface roughness and cost of casting. Water glass method dewaxes into the high-temperature water, and the ceramic mold is made of water glass quartz sand. Silica sol method dewaxes into the flash fire, and silica sol zircon sand makes the ceramic mold. Silica sol method costs more but has the better surface than the water glass method.

The process can be used for both small castings of a few ounces and large castings weighing several hundred pounds. It can be more expensive than die casting or sand casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required.
