Okplast Sarl, based in Congo, is a leader in manufacturing polymer based pipes and fittings for water infrastructure. Reliable quality assurance is essential for their products to withstand tropical climates and meet international performance standards. To enhance their QC lab, Okplast partnered with Testron Group to deploy a suite of precision instruments:-
- TT‑MFI 450A Melt Flow Indexer
- TT‑MW Halogen Moisture Analyzer
- TT‑O300 Industrial Drying Oven
- TT‑ACA220 Muffle Furnace (Ash Content Apparatus)
Challenge:- Ensuring Complete Material Quality from Raw Pellets to Final Products
Okplast’s QC team needed to validate:-
- Consistency of polymer melt behavior
- Moisture content in raw materials and pellets
- Efficient drying of critical components
- Ash content in final products
They required a set of complementary instruments:-each authoritative in its function:-to achieve faster, more accurate, and fully documented QC processes.
TT‑MFI 450A Melt Flow Indexer – For Melt Flow Control
Key KPIs:- Melt mass flow rate (MFR), polymer** melt consistency based on ISO 1133 / ASTM D 1238**.
Why it matters:- Melt flow determines processability and mechanical properties. The TT‑MFI 450A is a compact yet precise melt flow index tester that delivers MFR readings within ±0.5 °C accuracy, automatic rod cutoff, and timers accurate to 0.01 s.
Results:- QC cycle time dropped from 45 to 15 minutes; material rejects reduced by 40%, increasing extrusion yield.
TT‑MW Halogen Moisture Analyzer – For Moisture Control
Standards applied:- Gravimetric moisture measurement from ISO/National standards.
Moisture content affects printability, bonding, and performance. The TT‑MW is a halogen moisture testing machine with 5″ touch screen, German HBM sensor, halogen heating, and built in data logging.
Results:- Moisture check time reduced from 2 hours to 10 minutes per batch; data traceability improved drastically.
TT‑O300 Industrial Drying Oven – For Component Conditioning
Core need:- Fast, uniform drying before coating or testing.
The industrial drying oven delivers precise control up to 800 °C (customizable) with USB/Ethernet logging, ISO17025 calibration, and safety features.
Results:- Drying cycles shortened by 70%; throughput increased; batch to batch variations eliminated.
TT‑ACA220 Muffle Furnace (Ash Content Apparatus) – For Residue Analysis
Application:- Measuring ash content in polymer blends:-ensuring purity and filler levels.
The ash content tester with micro PC control, PID temperature regulation, and robust safety features produces uniform temperature and near zero variability.
Results:- Ash analysis now completed in under 6 hours versus 24+; QC documentation is automatic and compliant.
Integrated Workflow:- A Tabletop Lab Transformation
Here’s how the four systems work together in Okplast’s QC cycle:-
| Stage | Instrument | Key Metric | Benefit |
| Pellet Melt Behavior | TT‑MFI 450A | MFR | Predictable extrusion performance |
| Moisture in Raw Material | TT‑MW | Moisture % | Avoids defects due to trapped moisture |
| Precoating Drying | TT‑O300 | Moisture removal | Reduces cycle time, ensures consistency |
| Ash Content Analysis | TT‑ACA220 | %Ash | Confirms purity and formulation control |

Long Term Gains and Future Outlook
With the integration of the Melt Flow Indexer, Halogen Moisture Analyzer, Industrial Drying Oven, and Ash Content Apparatus, Okplast Sarl is not just optimizing short term testing efficiency but laying the groundwork for long term process stability and regulatory compliance. These material testing instruments have enabled the QC team to move from reactive testing to predictive quality assurance, helping forecast performance issues before they reach the production line. This shift is pivotal for a growing manufacturer in Africa’s competitive pipe and plastic product market. With real time data logging, scalable reporting, and modular expandability, these systems are now seen as strategic assets rather than just tools. Testron’s equipment ensures that as Okplast scales production and enters new global markets, their quality standards will remain consistently high:-meeting every ISO and ASTM specification with confidence.
Impact:- Quality, Speed & Regulatory Green Lights
Okplast now produces reliable, high performing pipes with minimal QC bottlenecks and full traceability. The integrated suite ensures that every batch meets local and international standards without delays or guesswork.
