Batch Weighing System Results: Real-World Case Studies

How rubber, silicone, and chemical manufacturers reduced batch rejections, achieved compliance, and increased throughput with Gomaplast batch traceability weighing systems.

Rubber Compounding

EPDM Compounder Eliminates Batch Rejections and Cuts Audit Time by 80%

Challenge

A mid-size EPDM compounding facility running 70+ batches per day was experiencing a 1.5% batch rejection rate due to manual weighing errors. Audit preparation required two full days per quarter, pulling operations staff off the floor.

Solution

Gomaplast GMI semi-automatic batch weighing system with 10-station carousel, RFID operator authentication, barcode ingredient verification, and automatic digital batch records exported to their ERP.

"The system paid for itself in under 14 months. Between material savings and the elimination of a full rework station, the financial case was straightforward."
— Operations Director, EPDM Compounding Facility
Medical Silicone

Medical Silicone Manufacturer Achieves GMP Compliance with Automated Batch Records

Challenge

A medical-grade silicone manufacturer required complete, auditable batch records for every production run to satisfy their ISO 13485 quality system and customer audit requirements. Their existing paper-based process was generating incomplete records and requiring extensive manual reconciliation.

Solution

Gomaplast GMI with PLC recipe management, RFID-enforced ingredient verification, automatic weight capture, and digital batch record generation integrated with their quality management system.

Specialty Chemicals

Specialty Chemical Blender Scales from 40 to 100 Batches Per Shift Without Adding Headcount

Challenge

A specialty chemical blender was facing growing order volume that their manual weighing process could not support without adding operators. Labor market conditions made hiring difficult and expensive.

Solution

Gomaplast GMI custom batch weighing system configured for their specific ingredient range and bin layout, with ERP integration to automatically receive production orders and return completed batch data.
