Moving an Injection Mould Between Suppliers: The Tool Transfer Guide

Updated: 2026-10-22

Moving an existing mould requires a commercial release and a technical requalification plan. Treat transport as one step in the transition. Before the tool leaves its current location, establish that the receiving site can install it, operate it safely and demonstrate acceptable parts without relying on undocumented assumptions.

What must be settled before shipping?

Confirm the identified tool, its ownership and agreed release conditions with the relevant parties. Check whether the transfer includes a complete mould, inserts in a shared base, a hot-runner controller, gauges and auxiliary equipment. Payment for tooling alone does not resolve every access, custody or release term. Resolve disputed rights with the responsible parties or advisers before scheduling collection.

Agree responsibility for packing, lifting, corrosion protection, insurance, freight and damage assessment. Photograph the tool and inventory loose components, controllers, spares and documents. Record existing damage and unresolved faults so arrival inspection does not become a dispute over when a problem occurred.

What belongs in the handover package?

Provide current part and tool drawings, revision history, cavity map, insert and wear-part details, hot-runner specifications, electrical diagrams and cooling circuits. Add material grade, drying/conditioning instructions, the last approved process record, cycle and output history, repairs, maintenance records and known quality issues. Missing records are an uncertainty to assess, not evidence of a healthy tool.

Include approved reference samples, the latest cavity-level dimensional report, cosmetic standards, fixtures, control plan and outstanding deviations. Identify which documents describe the current physical tool; an original build drawing may omit later repairs or modifications. Keep a controlled copy with the buyer rather than relying only on supplier-held files.

How is machine compatibility assessed?

The receiving team should compare the actual mould and process with the selected machine configuration. Check mounting and tie-bar space, mould height, opening stroke, ejection travel and interfaces, lifting capacity, nozzle/locating interface, core pulls, cooling and electrical/controller connections. Include take-out automation and access for maintenance.

Assess shot volume and injection-unit suitability using the exact resin, screw configuration, required flow and pressure, residence time and processing conditions. A generic 20–80% shot-size band is not a universal acceptance rule. Check clamping requirements and all relevant machine limits; matching the old machine's nominal tonnage alone does not prove compatibility. Use the machine manufacturer's installation and performance data for the actual configuration.

What happens after arrival?

1. Reconcile the shipment against the inventory and document condition before installation.
2. Agree any repair or interface adaptation, its cost and who authorises the work.
3. Establish a controlled trial with the specified material and recorded process conditions.
4. Compare identified samples from every cavity against the released requirements and previous baseline.
5. Close deviations, complete the agreed qualification and obtain written release before relying on repeat supply.

Old settings are a starting reference, not proof that a different machine reproduces the same process. Recheck product function, cosmetics and agreed critical dimensions; decide with the customer which capability studies, control-plan updates or formal reapprovals are needed. Use the sample-approval pack to keep the evidence and release decision together.

How should cost, continuity and second sourcing be planned?

Request separate allowances for assessment, freight, interface work, repair, trials, resin, measurement and qualification. Build the schedule around actual availability and findings. A universal refurbishment price or “four to eight weeks” promise hides the largest unknowns: condition, missing documents, technical modifications and approval requirements.

Calculate the stock bridge from expected demand and a reviewed transition schedule; include a contingency and the consequences of a late approval. A duplicate mould at another site can reduce dependence on one tool, but continuity still depends on qualified equipment, material availability, capacity and maintained tooling. It is not guaranteed by a second mould alone.

Sources and project assessment

PTI's transfer programme illustrates agreed refurbishment and validation scope. ARBURG technical data provides model/configuration-specific performance and installation information. These are external references, not a Nordmould machine list or service guarantee.

Review the FAI/PPAP requirements and tooling options, then send the tool and part records for a project-specific feasibility and scope discussion.
