Wholesale & OEM
Wholesale, OEM & Custom Manufacturing
You are buying from the factory, not from a reseller.
WLGQ is the consumer brand of Dongguan Sunlian Electronic Technology Co., Ltd. — established 2017, 240+ employees, production bases in Dongguan and Hunan, with an in-house reliability laboratory and in-house injection moulding.
Because we manufacture rather than trade, we can quote factory-direct pricing on our full catalogue, and we can develop custom parts to your specification.

Why order from us instead of a trading company
A trading company buys from someone. You pay their margin, and you have no way of knowing whether the part that reaches you was made in the same factory as the sample. Here, the sample and the shipment come from the same line, under the same test procedure, and we will show you the lab.
- Full test documentation — available on request
- Private labelling — neutral or custom packaging, custom SKU structure
- Custom moulding — from drawings or a sample
- Direct factory communication — you deal with the engineers, not an intermediary
