Use five review gates to keep a vertical injection molding purchase tied to documented requirements. Each gate should produce a record of confirmed items, unresolved questions and the person responsible for follow-up.
Gate 1: Freeze the Application Inputs
Collect the part and mold drawing revisions, material grade, cavities, shot information, inserts, critical quality requirements and accepted output target. Identify intended product changes separately from the current approved scope.
Gate 2: Confirm Technical Fit
Review clamp requirements, mold dimensions and movement, usable shot, injection capability and plasticizing demand for the selected model and options. Check insert loading, table movement, unloading and the complete protective and integration arrangement.
Do not turn an unexplained pressure-and-area formula into a final tonnage recommendation. Confirm the units, total projected area and the process basis of any estimate, then review the actual tooling and machine. Thermoplastic, LSR and other thermoset packages require their own compatibility checks.
Gate 3: Agree Trial Evidence
Define the material, mold, inserts, auxiliaries and inspection methods. Record the complete cycle, accepted output and quality results under representative conditions. For energy, define the equipment boundary and measurement period; a generic 30%–70% savings range is not evidence for your project.
Gate 4: Align the Delivery Scope
Reconcile quotation options, exclusions, documents, installation, training and support. Allocate site preparation and machine/mold/automation integration responsibilities. Confirm which interfaces and functions are included now and which require a separate future engineering review.
Gate 5: Verify the Installed Cell
Check delivered identification and configuration, site connections, commissioning records and the agreed acceptance results. Record remaining actions, documentation and training needs before the applicable project handover.
Review Questions
Does Buying Spare Capacity Make a Project Future-Proof?
No. Future parts and automation need defined requirements and compatibility review; a larger machine or unused connector alone does not establish readiness.
Who Should Own the Checklist?
Assign a project owner and involve the people responsible for tooling, production, quality, maintenance and site integration as relevant.
Use the detailed application checklist, budget worksheet and delivery and acceptance plan at the corresponding gate.
