2006
Local Heat Treatment Roots
Chuzhou Kangtai Metal Heat Treatment Factory began serving local agricultural machinery and hardware manufacturers, earning trust through practical process knowledge and reliable work.
National High-Tech Enterprise
From heat-treatment practice to a verifiable manufacturing system.
Founded in 2019, Dongte builds on Chuzhou's local heat-treatment experience and coordinates mold manufacturing, machining, heat treatment and inspection within one project workflow.
Company Development
From Heat Treatment Craft to an Integrated Manufacturing System
Dongte's manufacturing foundation grew out of long-standing heat-treatment practice in Chuzhou. According to company records, Kang Jiahao founded Chuzhou Kangtai Metal Heat Treatment Factory in 2006 with RMB 300,000 in start-up capital. Working with basic equipment and hands-on process knowledge, the workshop supported local agricultural machinery and hardware manufacturers and built its reputation on quality and keeping its word.
On July 16, 2019, his son Kang Shenchuan established Chuzhou Dongte Mold Co., Ltd. The new company did not simply reproduce the earlier workshop model. It extended that heat-treatment experience into mold manufacturing, precision machining and process control. Public registration records show that Kangtai's investor changed in 2020 and Kang Jiahao exited the operation, while the manufacturing knowledge and quality mindset continued to evolve within Dongte's newer system.
The family relationship and company history in this section follow information provided by the company. Registration, certification and patent details follow public records. Dongte's 2019 registration lists No. 388 Anqing West Road; the current factory-visit address is shown on the Contact page and should be confirmed before travel.
2019
The Second Generation Begins the Upgrade
Kang Shenchuan established Chuzhou Dongte Mold Co., Ltd., extending the business scope from heat treatment into mold manufacturing, metalworking and precision machining.
2020
The Earlier Operation Changes Hands
Kangtai's registered investor changed and Kang Jiahao exited the operation. Its accumulated understanding of materials and heat treatment continued to develop within Dongte's new system.
2023 to Present
A More Systematic Operation
Recognition as a National High-Tech Enterprise and inclusion in the Science and Technology SME program reflect a shift toward equipment-led, documented and repeatable manufacturing.
The Quality Mindset Continues. The Methods Have Evolved.
Production has moved from operator-dependent control toward stable delivery supported by equipment, defined processes and retained records.
Process Base
- Early Foundation
- Essential heat treatment such as quenching and tempering
- Dongte Today

Continuity does not mean reproducing an old workshop model. At Dongte, it means turning a practical understanding of materials, temperature and dimensional control into clearer process requirements, more stable production and inspection records agreed for each project. Customers receive more than a promise based on experience. They receive a manufacturing process that can be reviewed and verified.
