オーエヌ工業 List of Products and Services

We propose suitable casting processes tailored to product shapes and specifications, from alkaline phenolic casting to lost wax casting. Subsequently, we implement defect countermeasures unique to castings, such as shrinkage cavities, gas defects, and inclusions, using analysis techniques based on this casting simulation. In this document, we present examples where casting defects were improved through casting simulation. The information is clearly presented with diagrams and photos, so please take a moment to read it.

This document provides a gentle explanation of our alkaline phenol mold process. Alkaline phenol molds are a type of self-hardening mold that generally refers to a molding method and mold that hardens at room temperature without external heating or catalytic gas ventilation after molding. Compared to other self-hardening molds, it has gained attention and become widespread as an effective process for improving the working environment and enhancing casting quality.

"Lost wax casting" is a casting method in which molten metal is poured into a mold (wax) that faithfully reproduces the shape of the original model. Due to its excellent dimensional accuracy, it allows for the creation of shapes from the material, reducing processing costs, and results in a uniform and beautiful surface finish. Our domestic factory and overseas partner factories will meet your needs. 【Products suitable for lost wax casting】 ■ Weight: Approximately 1kg to 10kg ■ Dimensions: Small products around 200mm ■ Quantity: Large lots of around 100 pieces ■ Prototype delivery time: Approximately 4 months after order *For more details, please refer to the PDF document or feel free to contact us.
