Six questions that separate a factory from a reseller
None of these require a factory visit. All of them are hard to fake consistently across a few emails.
- Which specific machine makes this part? — a manufacturer names the tonnage and the machine. A reseller says 'our partner factory' and changes the subject.
- Can you change the inner width without new tooling? — if the answer is always yes with no cost, they are not tooling anything — width changes usually mean an insert or a new mould.
- Whose material is it, and what grade? — PA66+GF30 is a category, not a grade. A manufacturer can name the compound and the supplier; a reseller repeats the category.
- Show me the cycle test rig — a photo of the actual rig, with the model number visible. Test reports without a rig are usually a template.
- Which address would an auditor visit? — one address, or none. A 'factory' that turns out to be an office is the most common finding in a first audit.
- Who signs the drawing? — the same person who can stop a production run. If the drawing comes from a sales address with no engineering counterpart, you are buying from a trader.
What we are, precisely
One factory in Yueqing, Zhejiang — that is the only manufacturing site and the only address we can host an audit at. Shenzhen and Changzhou are sales offices. We say this because a number of listings for similar products imply a local plant that does not exist, and buyers discover it at the audit.
Approximately 70 injection moulding machines, 3,000+ moulds, in-house material compounding, IATF 16949. The certificates are on the about page as original PDFs, not as re-keyed numbers.

Where we lose, honestly
Against the large European brands we are not going to win a specification that names their part number, and we do not try. Their catalogue depth, their application engineering and their global stock are real advantages, and a buyer who needs a chain in three days in Ohio should use them.
Against domestic competitors we are not the cheapest. If price per metre is the only variable, someone will always quote lower — usually with a lower glass content, thinner side plates, or a pin clearance that works in the sample and hammers in production.
What we compete on is the middle ground: a size that is not in anyone's catalogue, a drawing returned in days, test data that matches the part you receive, and a factory you can actually visit.
How a first order usually runs
Most new relationships start with one size, not a container. That is fine and we would rather it did.
- 1. Requirement — stroke, cable list, speed, environment. A photo of the existing installation is often faster than a form.
- 2. Proposal — a specific model with drawing and, where relevant, the test data for that series — not a catalogue page.
- 3. Sample — stock sizes ship for evaluation; custom sizes go to tooling after drawing sign-off.
- 4. Production — batch with the agreed material grade; certificate of conformity on request.

Questions buyers ask at this stage
Are you a factory or a trading company?+
A factory. One manufacturing site in Yueqing, Zhejiang. Shenzhen and Changzhou are sales offices. If you want to audit, Yueqing is the only address that will show you a production line.
Will you send samples before we order?+
Yes for stock sizes. For custom sizes we produce a sample after drawing sign-off, because a sample made without agreed dimensions is not useful to either side.
What certifications do you hold?+
IATF 16949 and ISO 9001, with the original certificates on the about page. Separately, the cleanroom model WWC.28.65 in white was tested by Fraunhofer IPA to ISO Class 1 — that report covers one model, not the whole range.
Can you make a size that is not in your catalogue?+
Yes, for inner width and brackets. Height changes usually require a new mould and are quoted separately. Send the drawing and we will tell you which of the two it is.
Do you sell to distributors?+
Yes. Terms depend on whether you are stocking a region or reselling into projects — ask and we will be specific rather than sending a generic dealer policy.
Ask for a factory audit date
If the audit matters more than the price, tell us the month you plan to travel. We will confirm the Yueqing schedule and send the document package in advance.
