## How we think

What does quality mean at Xintai E-coat?

We stand on three things: **consistent coating thickness, salt spray resistance and insulation resistance**. The value of electrocoating is not that the paint goes on, but that every part in every batch is the same — and that comes from stable pretreatment, tightly controlled bath parameters and batch-by-batch testing, not from sorting afterwards.

How do we work with customers?

We want to be **one link in your process chain**, not just an outside contractor. So we ask about the operations before us (stamping, die casting, CNC, MIM sintering) and the assembly requirements after us, and we settle coating thickness tolerance, racking points and masking needs at sample stage — before they turn into rework in volume.

What does the shop floor demand of the team?

Electrocoating is three parts paint and seven parts discipline. The shop floor stays clean, bath parameters are logged and checked at fixed intervals, racks are maintained and replaced on schedule, and test data is archived and traceable. These look like basics, and they are exactly where batch consistency comes from.

## Frequently asked questions about the company

### How are Dongguan Xintai Metal Surface Treatment and Dongguan Xintai Coating Technology related?

Dongguan Xintai Metal Surface Treatment Co., Ltd. was founded in October 2024. Its predecessor, Dongguan Xintai Coating Technology Co., Ltd., was established in 2014. To accommodate growth, in 2024 the predecessor **relocated in full** to Dalang Town, Dongguan, and Dongguan Xintai Metal Surface Treatment Co., Ltd. was incorporated, taking over the business, the engineering team and the customer base. They are separate legal entities on the company register, and a succession and upgrade relationship in business terms.

### How large is the plant, and how many production lines are there?

The plant covers **3,200 m²** and runs a clean, well-organised shop floor with **two automatic and two manual e-coat lines**, four in total. The automatic lines carry stable high-volume work; the manual lines handle low-volume, multi-batch and complex-shaped sampling and pilot runs.

### What inspection equipment do you have?

We invest in production-grade inspection equipment, including a **Konica Minolta spectrophotometer from Japan**, **a ZGM gloss meter from Switzerland**, **Fischer coating thickness gauge from Germany** and more. Together they quantify color difference, gloss and coating thickness, and support salt spray and insulation resistance testing. The full list (11 instruments, with make and model) is on the [inspection & testing equipment](equipment.html#lab-equipment).

### Which management systems are you certified to?

We are certified to **ISO 9001:2015 Quality Management System** and **ISO 14001:2015 Environmental Management System**, both with a scope of **electrodeposition coating**; we also hold a pollutant discharge permit (valid until 2030). Certificate scans are in this page's [Certifications](#cert-gallery).

If you work to another system such as IATF 16949, tell us at project stage and we will support the process.
