Service commitment — the number of days we say is the number of days you get

Only what we can actually deliver is written here. What is written here, we measure ourselves against.

Reply within 24 hours

Enquiries, emails, drawings and questions are answered within 24 hours; a quotation follows within 3 business days, with a clear lead time and sampling plan.

Sampling: plan and lead time quoted case by case — in writing

Samples differ too much for one blanket promise, so we do not make one: you receive a sampling plan and a sampling lead time, with the number of days written down. A simple part reusing existing tooling is not the same as one needing new tooling or a colour match, and neither is the same as a multi-part assembly or one requiring outside testing — your quotation states which one you are getting. Once we have written a number down, we deliver to it.

Complaints: handled with the 8D method, one report per case

If something goes wrong we work it through 8D (eight disciplines) — contain first, then find the root cause, then prevent recurrence — not "rework and move on". Every case gets a report, a named owner and a closed-out record; the documents involved (work instructions, inspection standards, drawings) are updated and traceable.

How 8D runs (eight disciplines)

D1	Team — name the owner; bring in quality, production, engineering
D2	Describe the problem — when, which batch, how many, what exactly; photos and samples
D3	Contain — at the customer, in transit, in our warehouse, in production: handled separately at each point
D4	Root cause — two questions: why did it happen, and why did it escape
D5	Permanent fix — change the process, tooling, incoming material or standard; not just rework
D6	Implement & verify — make it real, then prove it with data
D7	Prevent recurrence — update the documents (work instruction / inspection standard / BOM / first-article rule)
D8	Close — customer confirmation, then archive

About response times — the honest version. How many days each step of an 8D should take is being set against what our workshop can actually sustain; we will not publish a number we cannot keep. Those firm response times will be added to this page once confirmed. Until then, the reply-by point for any individual case is told to you when the case is opened.
