About SANEI
One of China's earliest specialist manufacturers of wax-injection machines, SANEI has also established deep expertise in jewellery casting equipment. Today, both product lines support production in factories around the world, combining proven engineering, stable performance, reliable operation, and practical ease of use.
A Leading Name In Wax Injection And Casting, From Asia To The World
SANEI was among the first manufacturers in China to specialise in wax-injection machinery for jewellery production. Over more than two decades, that early focus has grown alongside extensive casting-machine development, creating two core equipment lines used by jewellery manufacturers across Asia and international markets.
Today, SANEI wax-injection and casting equipment is exported to countries around the world and deployed in volume by manufacturers that depend on repeatable output every working day. In comparative machine trials conducted by jewellery producers, SANEI has repeatedly achieved first-place results—recognition built on stability, reliability, production efficiency, and operator convenience.
We believe a machine earns trust through years of work on the factory floor. That is why SANEI continues to refine its engineering around real production conditions. Both our wax-injection and casting machines use genuine, Japan-made components. Every improvement serves the same goal: dependable equipment that helps customers produce more confidently, consistently, and efficiently.
Consistent pressure, temperature, and cycle control help production teams achieve repeatable wax patterns and casting results across demanding day-to-day workloads.
Our machines are developed for sustained production use, where dependable operation and predictable output matter more than specifications on paper.
Clear controls and practical workflows reduce operator complexity, support faster training, and make high-volume production easier to manage.
Feedback from jewellery factories is carried back into engineering, testing, interface design, and the next generation of SANEI equipment.
Established in Guangzhou in 2002 with Japanese investment, SANEI is one of China's earliest specialist manufacturers of wax-injection machines, with deep engineering expertise in jewellery casting equipment as well.
SANEI wax-injection and casting machines are shipped internationally and adopted at scale by jewellery manufacturers, from individual production lines to large factory installations.
Across both wax-injection and casting equipment, SANEI consistently uses genuine, Japan-made components and pursues a high standard of manufacturing quality and long-term operating reliability.
Our Thailand Base For Southeast Asia Equipment And Support
From our Thailand base, SANEI Bangkok combines regional communication and practical warehousing to support equipment selection, stock coordination, project delivery, handover, and after-sales throughout Thailand and across Southeast Asia.
As part of SANEI Bangkok's joint-venture structure, KYG Machinery helps extend the available range beyond SANEI's core equipment to other jewellery machinery, workshop tools, spare parts, and production consumables.
Founded in Guangzhou in 1988, KYG Machinery maintains an international machinery and consumables supply network.

Machines sold from 2005 to 2024, with more than 1,000 enterprises using the installed base.
Units sold since the VIC-2 entered the market in 2019.
We were established in May 2002 in Guangzhou, China, with Japanese investment. We began with repair of imported casting equipment and sales of domestic jewellery casting equipment.
From 2005 onward, we developed digital wax injection systems and semi-automatic wax injection solutions focused on finer wax patterns, fuller claws, and higher production efficiency.
Between 2005 and 2024, our wax injection machines sold more than 10,000 units and are used by more than 1,000 enterprises.
We started developing the VIC-2 vacuum pressure casting machine in 2018 and began sales on April 26, 2019. More than 5,000 units have since been sold.
In early 2023, we began developing the Honor PRO LCD-screen wax injection machine. It entered customer factory testing in June 2024, with six months of testing showing higher efficiency, finer wax parts, and easier operation.
From September 2024, we also upgraded the interface of the existing digital wax injection machine. The 2025 Digital Honor edition is designed to improve both productivity and day-to-day ease of use.
