Introduction: Moving to the Commissioning Stage
Let us take our journey to the next step.
In our previous article of Mould Lifecycle Management (MLM), we discussed the planning stage. Stakeholders / Key Decision Makers (KDM’s) have given their green signal to move our train to the next station — a station called Commissioning.
Journey is, of course, more important than the destination.
Similarly, the pathway to a successful production mould truly comes to life only during the production run.
Commissioning Stage: Overview and Importance
The output of this stage is a production mould supporting your brand/company by syncing it with market demands.
What begins as an idea during planning starts taking tangible shape during commissioning. This is the stage where design intent is converted into production reality, and where technical precision, alignment, and coordination determine long-term success.
Key Steps in Commissioning
Getting Started: Purchase Order & Initial Planning
Every mammoth structure starts with a humble brick. Commissioning too starts with a tiny step — a Purchase Order (PO) to your supplier, which acts as financial confirmation to move ahead with the mould building process.
Depending on whether the mould is for innovation or a repeat one, various parameters such as previous learnings, cycle time (CT) optimization, new technology integration, and maintenance-friendly design are considered.
Design Review & Technical Preparation
The mould manager must ensure completion of technical preparation work and bring all team members onto the same page with respect to the overall mould design.
Preparation includes:
- Sharing part details with the mould maker
- Issuing PO for required work
- Initial design review meetings for call-outs
- Mould-machine compatibility checks
- Any other project-specific requirements
Attendees typically include:
- Mould maker
- Mould manager
- R&D team
- SME
- Supplier
- Owner of the mould / brand (optional)
Alignment at this stage prevents downstream inefficiencies.
Prototype Manufacture & Trials
After design discussions, manufacture the prototype if it is a new product launch.
The prototype:
- May be a single or multiple cavity mould
- Is examined through trials to check mould functionality
- Validates functional, dimensional, and aesthetic aspects of the plastic part
This step may be skipped for repeat moulds if the mould maker is confident based on prior experience.
Production / Industrial Mould
Learnings from the prototype stage, if any, are discussed before finalizing the industrial mould design.
Upon approval, the mould maker reconfirms the lead time. Fresh learnings may influence timelines.
This is the stage where the product begins to take tangible form and readiness for production is built into the system.
Qualification & Roll-Out
Mould trial is the most critical checkpoint — the final gate before production approval.
The first mould trial is ideally conducted at the manufacturing workshop. Retrials should be conducted at the actual production site.
Trials occur in phases:
- Initial short trial: Understand mould functioning and part aesthetics
- Final trials: Validate mould steel dimensions, functionality, and part conformity
Upon stakeholder approval of samples, the mould is shipped to the production site, trialled again, and finally released for full-scale production.
Mould Trials: Scientific Injection Moulding & Process Optimization
As mould managers, we ensure that Scientific Injection Moulding tests are conducted and Balance of Fill is verified to optimize the process window.
Trialing samples at filling lines ensures compatibility across the entire filling and assembly system. This holistic approach prevents downstream integration issues and strengthens overall production reliability.
Documentation and Approval: Recording Trial Outcomes
Every mould trial must be thoroughly documented for future reference.
The documentation should include:
- Cycle time (CT) achieved
- Issues observed
- Corrective actions
- Critical mould dimensions
- Significant part dimensions
- Material details
- Process parameters
- Other mould-specific data
Once trials are successfully completed and samples approved by stakeholders, the mould is ready for shipment and production roll-out.
Commissioning Guidelines for Mould Managers
Structured execution ensures that commissioning remains predictable and controlled.
Regular Touchpoints
Since the mould manufacturing team and production team are often different, regular touchpoints are essential to update all stakeholders and address specific call-outs or requests.
Project Tracker & Key Milestones
A project tracker outlines the overall timeline and marks key milestones such as:
- Mould build completion
- Material shipment
- Mould trials
- Mould shipment
Additional milestones may include assembly machines, IML machines, and ancillary equipment readiness.
Action Tracker
Tracking open actions and ensuring resolution before target dates prevents delays during roll-out.
Meeting Notes
Maintaining formal records of weekly discussions provides clarity, accountability, and valuable historical reference for future projects.
