Cost reduction through method change and standardization for lost-wax casting (with examples).
Standardization with lost wax, shape changes are also possible. Weight reduction and cost reduction can also be achieved!
Parts that are being machined and assembled may be able to reduce costs. By integrating shapes made up of multiple parts, we aim to achieve cost reduction. It is also possible to achieve both weight reduction and cost reduction by removing unnecessary joint areas that were required for assembly. 【Shape】 Complex shapes and those with three-dimensional curved surfaces can be mass-produced at low cost. 【Material】 Special steel, stainless steel, copper alloys, and aluminum alloys can be freely selected. Additionally, since material changes can use the same mold, it is easy to compare and evaluate during the prototype stage. 【Strength】 By integrating adjacent parts and auxiliary components into a single casting, we can eliminate weak points caused by assembly and welding. For movable parts, weight reduction can eliminate unnecessary inertial forces, increasing durability. Thus, strength can be freely pursued from both the shape and material perspectives. 【Casting Surface】 There are slight differences depending on the casting material, but small parts are around 12S and large parts around 20S. 【Precision】 Compared to other casting methods, the precision is high, allowing for a reduction in the number of machining processes. We will consider and propose appropriate shapes together, so please feel free to consult with us first.

Proposal for standardization of LR common components We propose a shape change through the sharing of LR common components. By standardizing the shape, the mold production can be unified, and at the same time, the order quantity can be doubled, resulting in cost reduction through batch consolidation. We have also shortened processing time by adding relief (concave) to the bottom surface, which requires flatness. Material: S25C (precision casting) Size: 114×65×57
Detailed information
-
Conventional shape: A symmetrically shaped machined part. Management of two parts was necessary.
-
Lost wax shape: A proposal for shape modification through the sharing of common parts for LR. By standardizing the shared shape, the mold production can be unified into one type, and at the same time, the order quantity can be doubled, resulting in cost reduction through batch consolidation.

Company information
With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We obtained a U.S. patent for "MIM (Metal Injection Molding)" in 1991. We provide optimal proposals using various technologies and thoroughly support our customers' manufacturing! We specialize in complex three-dimensional shapes in small lots of various types and carry out everything from mold making to casting, machining, and simple assembly in an integrated in-house system. We supply products to various industries, including medical devices, semiconductors, machine tools, and aerospace. "Just make it, from one piece." We can propose a wide range of manufacturing methods from prototype production of one piece to mass production. We also enable time savings in searching for various suppliers and considering consultation destinations, becoming a true total cost reduction partner by proposing reductions in management costs related to consideration time and product costs. More than half a century ago, Castem began its casting business by handcrafting machine tools. Today, we have become a leading company in Japan for manufacturing general industrial components using lost wax casting and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.
