和の精密工業 List of Products and Services

At our company, we manufacture precision cast parts for various fields using the lost-wax casting method. Precision cast products are dense and have good strength, allowing for very high dimensional accuracy, and the surface finish is also much more beautiful compared to conventional casting. Additionally, parts with shapes that are typically difficult to process with just machining can be produced using the lost-wax method. This time, we will introduce the lost-wax casting method, which is our specialty.

At our company, we manufacture precision castings for various mechanical parts using the lost-wax casting method. Due to the precision and strength of the precision castings, we can achieve very high dimensional accuracy, and the surface finish is also reproduced beautifully compared to conventional casting. Additionally, parts with shapes that are typically difficult to process through machining alone can be produced using the lost-wax method. In this article, we will introduce the lost-wax casting method, which is our specialty.

By using the lost-wax casting method, we solve the pricing issues of metal products processed with machining, lathes, and multi-axis machining centers with overwhelming cost performance. Why is now the best timing? One of the disadvantages of lost-wax casting is that it takes time to set up. - There is no time for functional verification. - There is no budget for mold costs. - There is no time to try new methods. Despite being aware of the cost benefits, we have received inquiries from companies that are hesitant to take the plunge. Currently, production has drastically decreased due to the COVID-19 shock, and a V-shaped recovery is expected to take time. Conversely, it can be said that if companies do not increase their added value now, they will not be able to keep up with the V-shaped recovery. As added value, we confidently propose our lost-wax casting method. - We want to reduce costs for existing regularly processed products. - We want to make existing lost-wax casting even cheaper.

We would like to introduce examples of processing "lost wax" handled by Wa Precision Industrial Co., Ltd. Lost wax, often referred to as precision casting, can achieve overwhelmingly high dimensional accuracy and beautiful surface finishes compared to traditional casting methods. At our company, we can create products from a single piece without molds by performing 3D measurements from the actual item, creating drawings, and using 3D printing for wax molding. [Processing Examples (Excerpt)] ■ Material: SUS304 ・Lost wax + finishing process ■ Material: SKD11 ・Lost wax ■ Material: SKH57 ・Lost wax + finishing process *For more details, please refer to the PDF document or feel free to contact us.

"Lost wax" refers to the process of creating a prototype using wax, covering it with casting sand or plaster, and then heating it to melt and drain the wax, leaving a cavity that serves as a mold. By pouring high-temperature molten metal into this mold, parts and other items are produced. This process is called "lost wax casting." Additionally, due to its capability for precise casting, it is also referred to as "precision casting." 【Features】 ■ A mold is created using wax. ■ High-temperature molten metal is poured into the mold to create parts. ■ Suitable for precision machining. ■ Capable of forming complex shapes integrally. ■ Can eliminate machining processes, leading to cost reduction. *For more details, please refer to the PDF materials or feel free to contact us.

At Wa Precision Industries Co., Ltd., we are actively engaged in the manufacturing field where high precision on the sub-micron order is required. We are addressing a wider range of materials, including ceramics, working on extending the lifespan of molds, and promoting recycling. We have a proven track record in various mold components, including resin molds, press molds, die-cast molds, and connector-related products. Our strength lies in our ability to add the value of "mass production" to precision that can be described as "super." Mass production of fine slits through wire processing and discharge machining that accommodates small diameter holes of φ0.5 are prime examples of this. *For more details, please refer to the PDF materials or feel free to contact us.

At Wa no Seimitsu Kogyo Co., Ltd., we provide machine parts tailored to our customers' needs using the lost-wax method (casting method). The lost-wax method involves covering and solidifying a wax model with casting sand or plaster to create a mold. By pouring molten metal at high temperatures into the created mold, it is possible to manufacture highly precise parts at a low cost. In the lost-wax method (precision casting), the general tolerance for length dimensions is ±1%, so please use this as a guideline. *For more details, please refer to our catalog or feel free to contact us.

Before manufacturing expensive molds, we solve our customers' overall cost issues by creating prototypes through machining and 3D printing. *We also accommodate materials such as magnesium and aluminum used in die casting. Additionally, we support prototype processing for resin injection molding, vacuum forming, and more. If you want to confirm the shape, we will create it using 3D printing. If you want to seriously check the strength and actual material feel, we will handle it with machining. *For more details, please refer to the PDF materials or feel free to contact us.
