Industrial Platinum Palladium | Platinum and Palladium Precision Parts Factory One stop solution

Track prospects and core positioning of the plan

Yihui Casting has been deeply involved in the field of precious metal precision casting for 23 years. Targeting the core needs of a team of 5-10 people and a 50-100 square meter small and medium-sized industrial platinum palladium parts factory, we have created the first full process high vacuum closed industrial platinum palladium precision machining solution in China. All equipment is customized and developed for the physical and chemical properties of platinum group precious metals, achieving an oxygen free environment throughout the entire process from melting, casting to post-treatment. The comprehensive loss is controlled within 0.5%, and the casting density reaches 100%. The dimensional accuracy meets the highest level requirements of GB/T 15077-2019 "General Technical Conditions for Precious Metals and Their Alloy Castings", helping small and medium-sized factories break through technical barriers and enter the high-end industrial parts supply chain system.

Platinum group metals (platinum, palladium, rhodium, iridium, etc.) are irreplaceable core materials in high-end manufacturing industries such as aerospace, electronic information, petrochemicals, new energy, and healthcare due to their high melting point, high corrosion resistance, high catalytic activity, and good high-temperature stability. According to the Precious Metals Branch of the China Nonferrous Metals Industry Association, the annual average growth rate of industrial platinum group metal processing in China is 12%. However, the technical level of small and medium-sized processing plants is generally lagging behind, and more than 90% of factories cannot produce high-end industrial parts with precision requirements of ± 0.01mm or more and density requirements of 100%. They can only undertake low value-added rough processing business.

The processing of industrial platinum palladium accessories belongs to the typical high difficulty, high threshold, and high loss precision manufacturing field. Its core technical barrier lies in the melting points of platinum and palladium, which are 1772 ℃ and 1554 ℃ respectively. At high temperatures, they are prone to react with elements such as oxygen, nitrogen, and carbon; Liquid platinum palladium has poor fluidity, weak filling ability, and is prone to internal defects such as shrinkage, porosity, and porosity; Precious metals have extremely high value, and every 1 ‰ loss can cause huge economic losses. Traditional processes have been unable to overcome the technical bottlenecks mentioned above due to insufficient equipment vacuum, insufficient casting pressure, and poor temperature control accuracy.

Core technology pain points in the industrial platinum palladium parts processing industry

The quality of industrial platinum palladium accessories directly determines the performance and lifespan of downstream end products. Traditional processes have technical bottlenecks that cannot be overcome in the following core areas, which are also common problems that have existed in the industry for a long time:
