We make every CASTOVELLA caster in our own factory.
No trading desk and no bought-in wheels with a logo on the box: the range on this site is produced by us. Below is how we make it — the processes under our own roof, the specification control on every line, and the checks a batch passes before it ships.
Caster supply in China ranges from integrated manufacturers with their own casting, machining and assembly to trading storefronts with a logo and a rented desk. The products can look identical in photographs. We are the first kind: a factory. Everything below is our own production — what happens in-house, how a specification is held, and how a batch is checked before it leaves.
Made under one roof
The lines that make our casters — casting, machining, tread bonding and assembly — run in-house, under our own roof. That is what makes a specification more than a promise: the fork thickness, bearing options, hardness-controlled tread compounds and dimensional records behind every quotation are controlled where the caster is made, by the people who make it.
Built to a locked specification
- Specification format. Our factory produces to the locked-specification format: stated fork thickness, bearing options, hardness-controlled tread compounds, and dimensional records per batch.
- Standards basis. Specifications follow the ISO 22883 and EN 12527–12532 framework; load performance is tested per EN 12532 / ANSI ICWM conventions. These are specification and test-method standards — we describe them as 'built to / tested per', and we do not present them as certifications. Details: quality & testing.
- Sample first. No line is supplied at volume until its production sample has passed our sample protocol — dimensional measurement (including wheel width), hardness verification, and load testing per the stated convention.
- Export discipline. Export production is a standing part of our work: the documentation and packing discipline an export order needs is built into the line, not improvised per order.
Checked per batch
Because production stays in our own factory, the standard is checked per batch against a known baseline, and a drift is caught here — not discovered at your warehouse. What protects your order is not a photograph of a building; it is the locked specification, the tested sample, and batch traceability, and those are the things we put in writing.
