Company Profile

Shenzhen Super Smile-Tech Co., Ltd. (Super Smile-Tech) is a manufacturer of wire harnesses and cable assemblies, combining engineering development, custom production, and quality testing. Based in Shenzhen, the company has a production facility of approximately 3,000 square meters, more than 100 employees, and its own engineering and production teams, with the capability to deliver projects from requirements review and sample development through to volume production.

Our expertise extends from build-to-print production to translating complex connection requirements into practical manufacturing solutions. Connector and terminal selection, pin assignments and circuit definitions, wire lengths and gauges, branch configurations, shielding, and protection can all be customized around the interfaces, installation space, and operating environment of the customer’s equipment.

Our products and custom manufacturing services cover automotive diagnostic cables, heavy-duty vehicle harnesses, and turbo actuator cables, with applications extending to industrial automation, robotics, and low-voltage systems in new energy applications. We provide manufacturing support for power, signal, and control connections across different types of equipment.

In production, we bring material selection, wire cutting and stripping, terminal crimping, assembly, and inspection into a unified process. We perform 100% continuity testing and use confirmed drawings, samples, process documents, and inspection requirements to control manufacturing consistency in every batch.

Through direct collaboration between engineering and production at our own factory, Super Smile-Tech provides OEM/ODM services covering product customization, sample validation, volume production, and branded packaging. We support customers with clear technical references and a defined path for execution, from project development through to ongoing supply.

We solve connection challenges through engineering expertise and help bring our customers’ products to life through manufacturing capability. This is the value of Super Smile-Tech.
