Why Choose OUDA?

Four advantages behind our core competitiveness

Raw Material SuppliersUnchanged for 13 years. Reliable quality.
We source both imported and domestic materials, choosing large enterprises as long-term suppliers to ensure stable raw materials with assured quality.
When raw material prices fluctuate sharply, we use hedging to reduce business risk. We order only one month's supply, without stockpiling or speculation.

Continuous Product DevelopmentHigh-Quality Production
At the company's founding, two engineers were recruited to lead five people in establishing a product R&D department. Through continued development, we now have a highly skilled R&D team.
We build standardized workshops and conduct tests simulating customers' production conditions according to their requirements, ensuring that our materials deliver stable, enhanced performance in their products.

Fully Automated ProductionQuality phenolic resins for coated sand
We can produce resins to meet customers' special production requirements and provide corresponding resin-coated sand production processes and formulations.
Store in a dry place away from direct sunlight. Do not stack filled bags too high, to prevent caking.

Fast Dispatch in 3 DaysReliable, on-time dispatch
OUDA's logistics company and own transport fleet dispatch orders within 3–5 days of receipt.
We follow up monthly to assess customer satisfaction. If we cause a customer loss, appropriate compensation is provided after the loss has been verified.

About Us

Over ten years of progress. Discover our story.

Jinan Ouda Foundry Materials Co., Ltd. is located in Licheng District, Jinan, Shandong Province. With fifteen years of practical experience in studying resin-coated sand for hot-box foundry applications, the company offers a full range of technical support for coated sand used in non-ferrous metal, cast iron, cast steel, stainless steel and alloy castings, including independent research and development, production-process development, and equipment improvement and manufacture. We help resin-coated sand manufacturers solve technical challenges in development and production. To respond to recent changes in the foundry industry's requirements for coated-sand quality and technology, and with the aim of optimizing castings through coated-sand applications and increasing market share, the company began its transformation and upgrading in 2017. It established an operating model integrating the research, production, sales and technical support of auxiliary materials for resin-coated sand production. Our main products include phenolic resins for resin-coated sand, resins for foundry coatings, iron sand for resin-coated sand, red iron oxide, calcium stearate, flake graphite for resin-coated sand, amorphous graphite, hot-box release agents, high-temperature additives for steel castings and deodorizing agents. Over more than ten years of development, we have introduced German and Japanese technologies and adopted original German equipment. Our phenolic resins are non-toxic and environmentally friendly, with fast curing, high strength and high-temperature resistance. Our iron sand for resin-coated sand is produced using advanced technology. It has high purity, few impurities and a high Fe₃O₄ content, producing steel castings with a good surface finish, without orange-peel defects or subsurface porosity. Our iron sand for resin-coated sand has reached a 60% share of the national market. Guided by the principle of serving customers and achieving mutual success, we provide high-quality products and comprehensive after-sales service. The company has established a dedicated resin-coated sand testing laboratory, equipped with a full range of foundry-sand testing and analysis instruments and advanced experimental sand-mixing equipment. Combined with a professional R&D team, these resources allow us to provide coated-sand production processes and formulations, helping customers reduce production costs and improve product quality. Registered with the approval of the relevant national authorities, the company has strong production and technical capabilities. Our product ranges offer high quality at competitive prices, and our comprehensive service system has helped us establish long-term partnerships with many well-known companies in China and abroad.
