Die and mould manufacturers do not work like conventional mass-production factories. They usually manufacture customised dies, moulds, fixtures and tools in very small quantities, often just one or two pieces for each order.
These companies are also known as tool rooms. Every project may have a different drawing, BOM, material requirement, machining route, delivery schedule and production cost. Because of this variation, standard inventory or accounting software often fails to provide the planning and control they need.
Consider a shoe manufacturer that requires moulds for several shoe sizes. It may need only one mould for each size. Although all moulds belong to the same order, every size may have different dimensions, material requirements, machining time and trial conditions.
A manufacturing ERP for die and mould manufacturers should therefore treat each mould as an individual project and track it from customer enquiry to final dispatch.
Why Die and Mould Manufacturing Is Different
Mass-production companies usually work with standard products, repeatable BOMs and fixed production routes. Tool rooms work with customised orders where each project can follow a different production journey.
Orders are generally one-off or low-volume, so production must be planned project-wise instead of batch-wise. The customer drawing determines the dimensions, material, BOM, machining operations and inspection requirements. A small design change can affect material planning, machine allocation, production time and delivery commitments.
Production cycles can also be long. A mould may pass through design, cutting, CNC machining, VMC machining, EDM, wire cutting, grinding, heat treatment, polishing, assembly and trial before it is ready for approval.
High material costs and expensive machine hours make project-wise costing equally important. A small error in estimating machine time or rework can reduce the margin on the complete order.
Common Challenges Faced by Tool Rooms
Managing Multiple Custom Projects
A tool room may work on several unrelated moulds at the same time. Each project can have a different customer, drawing, priority, process route and due date.
Without a central system, teams often depend on spreadsheets, paper job cards and verbal updates. Managers then struggle to identify the current production stage, pending operations, material shortages and projects at risk of delay.
A project-based ERP gives the design, planning, production and management teams a common view of every mould under production.
Controlling Drawings and Design Revisions
Customer drawings often change before or during production. If an operator uses an outdated revision, the company may face incorrect machining, scrap, rework and delayed delivery.
The ERP should maintain the current approved drawing, previous revisions, change details, approval history and the production orders affected by each revision. This ensures that the shop-floor team always works with the correct document.
Scheduling Shared Machines
CNC, VMC, EDM, wire-cut and grinding machines are usually shared across several projects. A delay in one operation can affect many moulds waiting for the same machine.
The schedule should consider machine availability, current load, job priority, operation sequence, expected duration and delivery date. Tool rooms can also use the principles explained in production planning versus scheduling to separate long-term project planning from daily machine allocation.
Design Document to BOM Automation
Design-to-BOM automation is one of the most important requirements in die and mould manufacturing. It helps convert approved engineering information into structured production data without repeatedly entering the same details.
A typical workflow is:
Customer Drawing or CAD File → Design Review → Approval → BOM Creation → Process Route → Material Planning → Production Order
Drawings and CAD files can be attached to enquiries, items, projects and production orders. BOMs can then be created using standard templates, copied from similar moulds or imported through Excel and CSV files.
For example, a shoe mould manufacturer may copy the BOM of an existing shoe size and change only the dimensions, quantities and components that differ. Once the BOM is approved, the ERP can automatically calculate material requirements and identify purchase shortages.
However, a CAD drawing may not contain complete purchasing and manufacturing information. Design-to-BOM workflows can be automated through structured data, templates, imports and integrations, but an engineer should still review and approve the final BOM before production begins.
Important ERP Features for Die and Mould Manufacturers
Enquiry and Quotation Costing
Before accepting an order, the manufacturer must estimate raw material, standard components, machine hours, labour, design time, subcontracting, inspection and trial costs.
A connected manufacturing quoting software workflow helps maintain quotation revisions and compare the original estimate with the actual project cost after completion. This is important because even a small error in material weight or machine-hour estimates can reduce the final margin.
BOM and Process Route Management
Each mould may require a different BOM and production sequence. The BOM should include raw materials, standard parts, purchased components and manufactured items.
The process route should define the complete operation sequence, planned machine, expected duration and inspection requirement. Typical operations may include cutting, CNC or VMC machining, EDM, wire cutting, grinding, heat treatment, polishing, assembly, inspection and trial.
Since every mould is different, planners should be able to revise the route without affecting unrelated projects.
Material Planning and Inventory
Material requirements should be generated from the approved BOM before production starts. This helps the planning team identify shortages and create purchase requirements in advance.
The ERP should also reserve tool steel, plates, inserts, guide pillars, bushes, springs and other components against specific mould projects. This prevents the same stock from being considered available for multiple jobs.
Actual material issues should remain linked to the project so that planned consumption can be compared with actual consumption.
Off-Cut and Leftover Material Tracking
Tool rooms often work with expensive tool steel blocks and plates. After cutting, some leftover material may still be usable for another component or a smaller project.
The ERP should record the grade, dimensions, weight and storage location of each usable off-cut. This material can then be considered during planning, reducing unnecessary purchases and material waste.
Subcontracting Management
Processes such as heat treatment, coating, engraving, polishing and specialised machining are often outsourced.
A proper subcontracting management workflow should track the material sent, vendor, expected return date, actual receipt, rejected quantity, inspection result and vendor charges.
This keeps the outsourced process connected with the original mould project and gives planners early visibility into vendor-related delays.
Operation-Wise Production Tracking
Production should be recorded at every operation instead of only at the final stage.
The shop-floor team should record the start and completion time, machine used, operator, actual hours, rejection, rework and delay reason. This gives managers live project progress and allows them to compare planned and actual time for every operation.
It also helps identify where production is slowing down and which jobs are waiting for the next machine or process.
Quality, Trial and Rework Tracking
A mould is not always complete after assembly. It may require one or more trials before customer approval.
A common cycle is:
Assembly → Trial → Observation → Design Correction → Additional Machining → Reassembly → Final Trial
The ERP should record dimensional inspections, trial observations, customer feedback and non-conformance reports against each project. If a correction is required, the revised drawing, additional machining, rework time, material consumption and approval status should remain connected with the same mould.
This creates a complete history of why the project required rework and how it affected delivery and cost.
Estimated Versus Actual Costing
Tool-room profitability depends on accurate project costing. The ERP should compare estimated material, machine, labour, subcontracting and trial costs with the actual project expenses.
Cost area | Estimated | Actual |
Material | Quotation BOM | Material issued |
Machine cost | Planned machine hours | Actual machine hours |
| Labour | Estimated labour hours | Recorded labour hours |
Subcontracting | Vendor estimate | Actual vendor cost |
| Trial and rework | Planned allowance | Actual cost |
This comparison highlights excess material consumption, additional machine hours, rework cost and vendor cost variations. It also helps calculate the actual margin for every mould and improve future quotations.
Complete Die and Mould Manufacturing Workflow
A connected ERP workflow begins when the customer shares an enquiry, drawing or technical specification. The engineering team reviews feasibility, estimates the cost and prepares the quotation.
After order confirmation, the design is finalised and approved. The team then creates the BOM and process route, generates material requirements and plans purchase shortages.
Available material is reserved against the project, while machining operations are scheduled across the required machines. Production is recorded operation-wise, along with inspections, outsourced processes and delays.
Once the mould is assembled, the trial is conducted. Any correction or design change is tracked through revised drawings, additional operations and rework records. After customer approval, the mould is dispatched and the estimated cost is compared with the actual project cost.
Reports and KPIs for Tool Rooms
Useful reports include project progress, machine loading, pending operations, material shortages, subcontracting status, trial observations, rework cost and drawing revision history.
Management should also track on-time project completion, planned versus actual machine hours, material cost variance, machine loading, trial success rate, subcontracting delay and quotation versus actual margin.
These reports help managers identify delays and cost overruns before they become difficult to control.
Manufacturing New Moulds vs Managing Existing Tooling
Tool-room management may refer to two different activities.
The first is manufacturing a new die, mould or fixture. This requires enquiry management, design, BOM creation, material planning, machining, trial and project costing.
The second is managing existing tooling already being used in production. This includes tool issue and return, storage location, usage history, maintenance, repair and tool-life monitoring.
A complete manufacturing system should support both workflows while keeping their planning, costing and reporting separate.
