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 measures against casting-specific defects such as shrinkage, gas porosity, and inclusions using analysis techniques based on this casting simulation. This document presents examples where casting defects were improved through casting simulation. It 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, generally referring to a molding method and mold that hardens at room temperature without external heating or catalyst gas ventilation after molding. Compared to other self-hardening molds, it has gained attention and become popular as an effective process for improving the working environment and enhancing casting quality.

Lost wax casting is a method of casting where melted metal is poured into a mold (wax) that faithfully reproduces the shape of the original model. It offers good dimensional accuracy, allowing for the creation of shapes from the material and reducing processing costs, while the surface finish of the casting is uniform and aesthetically pleasing. 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 up to about 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.
