MANUFACTURING BUSINESS SINCE 2016
The workshop behind Alloyvanta.
Alloyvanta is the export brand of Weishangcheng Technology Co., Ltd., a machining business in Shenzhen.
We have been machining parts in Shenzhen since March 2016. What we kept running into was distance: overseas customers had good designs and no straightforward way to reach a workshop that would talk through the details. Alloyvanta, launched in September 2026, is our answer to that. The new brand and website build on that existing operation.
We run six services in our own workshop and coordinate specialist work through 300+ partner factories. The production route and inspection requirements are agreed for each project.
Zhiyu Jiang (姜志瑜) runs the company. He came up through design and the shop floor, and trained our team himself. Demanding parts are supervised by him in person.
