Lost Wax Precision Casting - MIM (Metal Injection Molding)

What is Lost Wax Casting?


Lost wax casting is a type of metal casting method that offers the greatest flexibility in shape and material.
Our lost wax casting technology is selected by various industries such as food, packaging, semiconductors, etc., as well as general industrial equipment.

Features of our Lost Wax Casting

Shape More flexible in shape compared to other manufacturing methods
Material Various types of steel, stainless steel, and aluminum
Quantity Small to large lots (tens to thousands of pieces)
Casting surface Approx. 12.5a (depending on product size and casting material)
Accuracy Higher dimensional accuracy compared to sand casting. Less machining is required, thus reducing machining costs and time.

Cost Reduction Examples

Mold Cost

Mold manufacturing cost is extremely low (about 1/5 of molds for plastic parts), and once made, the molds can be used semi-permanently.

Production Cost

Prototyping, Small Lot Production
Due to low mold cost, the cost per product is definitely lower than other manufacturing methods.

Mass Production
We can offer low price by selecting the best solution for each product.

Machining Cost

Machining is eliminated or greatly reduced. Cost advantage is significant for difficult to machine materials.

Assembly Cost

Assembly parts that are composed of multiple parts can be integrated into a single part, resulting in significant cost reductions.
