Guangzhou QLQ Enterprise Co., Ltd. is a Chinese manufacturer and exporter of surface-finishing lines and zipper-making machinery, operating since 2012. We build, install and support complete electroplating and painting lines for small metal hardware — zipper sliders, bag fittings, buckles, buttons and imitation-jewellery parts — and we supply the chemicals that run them.
At a glance: Manufacturer & exporter since 2012 · Own factory: Qingyuan 10,000 m² plant + Huadu Shiling plant, Guangdong, China · Exported to 70+ countries · 35 senior engineers · In-house mould precision to 0.02 mm · ISO 9001 quality system · CE compliant machinery · Factory audit and third-party inspection welcome.
Who are you — a factory or a trading company?
We are a manufacturer. Our own production bases are the Qingyuan plant (10,000 m²) and the Huadu Shiling plant, both in Guangdong Province, China. Because we own the metalworking, assembly and chemical-blending capability, we control lead times, spare-part supply and process troubleshooting ourselves rather than passing them to a third party.
Buyers are welcome to visit and audit the factory. We can arrange a live video walkthrough of the workshop, or receive your inspectors or a third-party inspection agency on site.
What do you actually build?
Two product families, one company:
| Product family | What it covers |
|---|---|
| Surface finishing lines | barrel plating, rack plating, anodising/oxidation; painting — barrel spray, rack/hanger spray, cold spray, electrophoretic coating (e-coat), resin dripping. Supplied as turnkey lines: tanks, rectifiers, automation modules, ovens, jigs, wastewater-conscious process design, installation, commissioning and operator training. |
| Own chemicals | brighteners, additives, grinding/polishing media and cleaning agents for the plating shop. Because we also run these lines, the chemistry is tuned to real production conditions rather than to a catalogue specification. |
| Custom automation modules | |
| Zipper machinery & hardware |
Which countries do you export to? Is the data verifiable?
We have delivered equipment and consumables to 70+ countries across South and Southeast Asia, the Middle East, Africa, South America and Europe. Our longest-standing markets include Bangladesh, India, Vietnam, Indonesia, Pakistan, Egypt, Turkey, Brazil, Mexico and Poland, and we run a dedicated Bangladesh sales and service base that supports customers across South Asia.
Our export activity is conducted under the legal entity name Guangzhou QLQ Enterprise Co., Ltd., so customs and trade records can be checked under that exact name on standard trade-data platforms. For buyers who need it, we can also provide shipment references, proforma invoices and previous export documentation for verification before an order is placed.
Are you on B2B platforms, and is it the same company?
Yes — and deliberately under one single company name. Our Alibaba International Station store has been trading since 2012 and is operated by Guangzhou QLQ Enterprise Co., Ltd. — the same legal entity that operates this website. When a supplier appears under several websites, the fastest way to check whether it is real is to confirm that the legal entity name, the address and the trading history all match across every channel. We make that easy on purpose.
Our brands — one company, four specialisations
Rather than one vague website trying to sell everything, each QLQ brand is focused on a single buyer problem. All four are owned and operated by Guangzhou QLQ Enterprise Co., Ltd.:
| Brand / website | Focus | Typical buyer |
|---|---|---|
| platingclub.com this website | Surface finishing: electroplating and painting lines for small metal hardware, plus own chemicals | Hardware factories setting up or upgrading a plating/painting shop |
| zippermachine.com | Zipper-making machinery and complete zipper factory solutions | Zipper manufacturers building or expanding a plant |
| goodzipper.com | Zippers, zipper tape and accessories for bags and apparel | Bag makers, garment factories, trading companies |
| zipperhardware.com | Zipper hardware and metal bag fittings | Bag and leather-goods manufacturers sourcing hardware |
How do you verify quality before shipping?
We work to an ISO 9001 quality management system and our machinery is supplied CE compliant. Where a certificate or declaration is relevant to your order, we issue it with the equipment documentation so it can be checked against the issuing body.
On the process side, every line we deliver is validated against measurable acceptance criteria rather than a verbal promise — for example salt-spray hours to white rust on a plated part, coating-thickness range, tape/adhesion test results and colour tolerance against an approved sample. We also supply an installation and operation manual, chemical technical data sheets (TDS) and operator training with each line, so your team can hold the same numbers after we leave.
What documents come with an order?
| Document | Purpose |
|---|---|
| Installation & operation manual | Line layout, utilities, start-up, shutdown, daily checks and maintenance schedule |
| Chemical TDS / SDS | Bath make-up, dosing, operating window, safety handling for our brighteners, additives and cleaning agents |
| Process parameter sheet | Target current density, temperature, pH, immersion time, coating thickness per part family |
| Acceptance criteria sheet | The measurable standard your QC and our commissioning engineer agree on before handover |
| Training record | Signed proof that your operators were trained on the line we installed |
| Certificate / declaration | ISO 9001, CE and other compliance documents applicable to the supplied equipment |
How is a project controlled from enquiry to production?
The sequence is deliberately fixed so nothing is left to interpretation: part drawing and sample review → process route proposal → bath/sample trial with reported results → line configuration and quotation → manufacture and pre-delivery inspection → shipment → on-site installation and commissioning → operator training → production support. During installation, a QLQ engineer stays with your team until the line hits the agreed output and quality figures. After that, you keep the same engineer as your technical contact for process upgrades, spare parts and chemicals.
What about environment, wastewater and compliance?
Plating and painting lines are only as good as their waste handling. Our process design separates concentrated rinses from low-concentration rinses so rinse water can be recycled back to the tank, and we integrate drag-out recovery and counter-flow rinsing to cut both chemical consumption and the load on your treatment plant. We size and specify the wastewater treatment and exhaust/scrubber scope together with the line, so the shop can meet the discharge and emission limits set by the local authority where it is installed — this is a standard part of our turnkey scope, not an afterthought.
Who will look after us after the sale?
Our 35 senior engineers work across mechanical design, electrical/automation, plating chemistry and mould making, so a problem gets routed to the right discipline instead of being answered generically. Support includes remote diagnosis, spare-part supply from our own factory, chemical re-supply with consistent formulation, and on-site visits when a process issue genuinely needs hands on the line. Customers who join us for a first line usually come back for the second and third — which is the only kind of reference we consider meaningful.
Talk to us
Send us a part drawing, a sample photo and your target output — we will come back with a process route, the numbers behind it and the line configuration we would build. If you are evaluating several suppliers, ask each of them the same questions listed above and compare the answers: who actually owns the factory, which legal entity carries the export record, and what measurable standard they will sign up to.
