Shenzhen and Changzhou are sales offices that handle orders and local support; they do not manufacture. Warehouses in Dongguan, Foshan and Shanghai shorten delivery times. Factory audits are arranged in Yueqing only.
2. Three checks: is this the official site?
Similar-looking sites do exist. Rather than ask you to guess, here is a set of checks you can run yourself. Pass all three and you are safe.
- 1
Check 1: read the domain in the address bar
The official domain is www.cnwslchain.com. Watch two things: whether the word chain has been swapped for another word or a pinyin spelling, and whether a suffix such as -cn or -china has been appended. The domain is always the part before the first single slash; ignore everything after it.
- 2
Check 2: look at the email domain
Our formal quotations, contracts, payment notices and shipping documents are sent from @cnwslchain.com only. If a "formal quotation" or a "change of bank account" reaches you from another domain, do not transfer money — call the official number and verify first.

Check 3: call the official number back
Official phone: 0086-0577-62328108. After any incoming call, dial this number yourself; if it connects and the person matches, you are talking to us. There is only one plant address: No. 2891 Ningkang East Road, Tiancheng Street, Yueqing, Zhejiang. Anyone offering a factory visit but unable to give a Yueqing address is not us.
3. How the brand relates to the company
"Weishilong CNWSL" is the brand of Zhejiang CNWSL Plastic Co., Ltd., used on precision plastic cable carriers, protective conduits, hoses and machine-tool operating elements. CNWSL is simply the company abbreviation, not a separate business.
The company was founded in 2010 under the registered name Wenzhou Weishilong Plastic Co., Ltd. and was renamed Zhejiang CNWSL Plastic Co., Ltd. in 2026. Certificates such as IATF 16949 and ISO 9001 are issued on a three-year cycle, so during the transition they may still show the former name. That is normal after a rename: it does not mean the certificate has lapsed, and it does not mean these are two companies.
There is one plant only, at No. 2891 Ningkang East Road, Tiancheng Street, Yueqing, Zhejiang. We develop our own moulds, do our own injection moulding and our own assembly — we are neither a trading company nor an OEM labelling operation.
4. About companies with a similar name
Several Chinese companies use "Weishilong" in their trade name, and a few websites use domains close to ours. None of them has an equity relationship with Zhejiang CNWSL Plastic Co., Ltd., none is authorised by us, and none acts as our agent. Their website content, prices and commitments do not represent us.
You do not need to memorise anything: run the three checks above — domain read character by character, email domain after the @, and one call back to the official number.
If you find a website misusing our company name, certificate images or plant photos, send the URL to info@cnwslchain.com and we will investigate.
5. Frequently asked questions
The questions customers ask most, answered once and for all.
- Which is the official CNWSL cable carrier website?
- www.cnwslchain.com. It is the only official website of Zhejiang CNWSL Plastic Co., Ltd. Both the Chinese site and the English site (/en) run on this domain. There is no second official site.
- Why do other Weishilong websites show up in search?
- Some Chinese companies use Weishilong as a trade name, and some sites use similar domains. They have no equity, authorisation or agency relationship with us. Verify on three points only: domain, email domain and plant address.
- Why does the company name on the certificate differ from the website?
- The company was renamed from Wenzhou Weishilong Plastic Co., Ltd. to Zhejiang CNWSL Plastic Co., Ltd. in 2026. Certificates follow a multi-year renewal cycle and may still show the former name during the transition. You can verify the certificate number with the issuing body.
- What can I download from the site?
- Product catalogue PDFs, the IATF 16949 certificate and other public documents are in the Download Centre. For selection, use the selection guide, or scan the WeChat mini-program code in the footer.
- Where is the factory, and can I visit?
- The plant is at No. 2891 Ningkang East Road, Tiancheng Street, Yueqing, Zhejiang, and visits can be arranged by appointment. Shenzhen and Changzhou are sales offices and do not host audits.
