Keep drawing revisions, call-offs and customer rejections attached to every part number.

Industrial buyers do not order parts. They order part numbers at a stated drawing revision, released through weekly schedules that the buyer reissues, often with quantities moved, before the last pallet has cleared your dock. When revision C replaces revision B, the old stock in the racks becomes either a problem or a sale.

Management software for plastic component makers keeps the revision, the tool, the schedule and the rejection log under each part number. Tell us which housings, caps and clips you mould, and each one gets its own tool list and its own view of the weekly schedule your customers keep reissuing. Start with one housing.

A buyer releases a drawing and a yearly volume. You quote the part, the tool ownership clause, the heat-staked inserts or brass nuts fitted afterwards and the packing in returnable trays, with each item priced separately. A first-article report with measured dimensions goes to the customer, and volume production is released only after the buyer has signed the sheet and returned it. The customer’s schedule then arrives weekly, and it changes.

On the floor, the press runs against that schedule, with rework such as deflashing, gate trimming and ultrasonic welding done in cells. Parts are counted into trays by kit, so one tray holds what one assembly needs. A delivery note rides with each load. A rejection arrives by email, sometimes months later. It carries a photograph of a short shot or a sink mark.
