Scoping a Cold-Chamber Die Casting Machine RFQ: Options, Exclusions and Buyer Checks
A buyer's guide to defining scope, options and exclusions when requesting quotes for a cold-chamber die casting machine for aluminum, with practical RFQ and acceptance questions.
Start by fixing the clamping tonnage you actually need within the listed 130–900 t series range, then state it as a required value rather than a preference. A machine sized at the low end may suit small aluminum parts, but the RFQ should ask each supplier to confirm the tonnage offered and the die size and shot weight it supports, so bids can be compared on the same basis.
Separate base machine from options in the RFQ. Ask whether the quoted casting system is cold chamber as specified, and list every option you expect to be priced separately, such as die change aids, monitoring or automation interfaces. For each, request a description and whether it is factory-fitted or retrofittable.
State exclusions explicitly: installation, foundations, utilities, dies, training and commissioning can otherwise be assumed by either side. In demonstrations and acceptance tests, agree measurable checks in advance, such as cycle consistency and repeatable clamping, and record the test conditions.
Before requesting a quote, confirm with the supplier the exact tonnage and configuration offered, which items are options versus standard, what the price excludes, and how acceptance will be demonstrated and documented.
