Plugging the Leaks: Managing Theoretical vs. Actual Material Consumption
In high-precision manufacturing like Plastic Injection Moulding and Rubber Moulding, material cost often accounts for over 60-70% of the total product cost. However, many plants struggle with a constant mismatch between what “should” have been used (BOM) and what was “actually” consumed on the shop floor.
Finsys ERP provides a robust framework to bridge this gap using advanced Backflush and Actual Consumption tracking.
The Problem: The “Material Variance” Headache – Theoretical vs Actual Consumption ERP
Most ERPs simply “backflush” material based on the Bill of Materials (BOM). For example, if you produce 100 units, the system assumes you used exactly 10kg of granules. But in reality:
-
Purging: Extra material is wasted during machine startup.
-
Rejections: Not all material becomes a finished good; some goes to scrap.
-
Flash & Runners: In moulding, the runners and flash often vary in weight.
If you only track theoretical data, your Physical Stock will never match your System Stock.
The Finsys Solution: Real-Time Variance Analysis
The video demonstrates how Finsys ERP handles the duality of production accounting: Theoretical vs Actual Consumption ERP
1. Theoretical Backflush (BOM Based)
The system automatically calculates the expected consumption as per the standard BOM. This serves as the “Benchmark” for every production batch.
2. Actual Material Issuance (Barcode Based)
Using scanners, the actual quantity of raw material issued to the machine is recorded. Whether it’s 25kg bags of Polymer or Compound batches in Rubber, every gram is tracked.
3. Variance Reporting (The “Truth” Report)
Finsys provides a live comparison. If the BOM says 10kg but the operator used 11kg, the system highlights a 10% negative variance. This allows the plant head to immediately investigate machine settings, mold issues, or operator inefficiency. [04:30]
Strategic Benefits for Moulding Plants
| Feature | Business Impact |
| Wastage Identification | Pinpoint exactly which machine or shift is wasting more material. |
| Accurate Inventory | System stock matches physical stock because actual consumption is booked. |
| True Product Costing | Calculate the actual cost per piece, including flash and purging loss. |
| Material Reconciliation | Easy month-end audits for expensive polymers and compounds. |
