About us

333 Diecasting Co.,Ltd

The company was established in 1973 under the name ‘Kriengkrai Metal Works’ producing metal molds for customers. A few years later the company started to manufacture its own window winders under different brands: 333, 3M and 3 bullets. The company also produced keys for hinged door branded ALTA and SCOTT and sliding door flush locks branded ROYALTY.

In 2002, The company has changed the name to K.K. Diecasting and expanded the business into manufacturing auto parts and electric parts for Thai-Japanese companies as called OEM (Original Equipment Manufacturer) The company was granted ISO 9001:2000 in that year.

In 2005, ‘333 Diecasting’ was founded by working independently from K.K. Diecasting and was  registered in 2007. Main products are Louvre window winders, aluminium Louvres,  door cylindrical locksets, door and window hinges, and door latches under branded ‘333’,  which were granted ‘Thai Industrial Standard’, to increase brand awareness. Main customer of ‘333’ product is Aur Arthorn project of National Housing Authority who owns more than 300,000 units all over Thailand.

During this time, ‘333 Diecasting’ had started to see the problems of door and window hardware at that time e.g. traditional and dated design, low quality product from using low cost materials.

In 2008, the company decided to develop new product branded ‘GUT’ and launched the product in 2009  which are sliding door and window locks and louvre windows that have been designed carefully to create stylish look while offering strength and durability by using high quality raw materials. Adjustments have been made to make installation easy and convenient (semi D.I.Y.). ‘GUT’ represents the alternative for architects, homeowners, housing project owners and door and window companies that are looking for high quality and unique product. It also adds value to door and window profiles for companies that want to create up market brand and unique selling points. The company was trusted and chosen by different well known projects e.g. Parichart, Mantana, Sarin City and many housing projects of ‘Land and House’. We also design and manufacture window and door locks for aluminium door and window companies.

At present, Ms. Sudarat Techakijkriengkrai is the Managing Director of ‘333 Diecasting’ with the vision and goal to develop production efficiency, product quality and staff performance continuously to meet the need of the customers at all time.
