In today’s competitive global market, manufacturing excellence hinges on two critical pillars: production efficiency and sustainability. For a uPVC fittings manufacturer in Kenya, grappling with inconsistent raw materials and significant production waste was a major roadblock to growth. This case study explores their journey of overcoming these challenges through a strategic partnership with Green PVC, transforming their operations, and setting a new standard for quality and efficiency.
The Challenge: Battling Inefficiency and Waste in Kenya
At the beginning of 2024, the Kenyan manufacturer faced a critical operational dilemma. Their production of ball valves and pipe fittings relied on locally sourced PVC compounds, which proved to be inconsistent and problematic. The primary challenges included:
- Excessive Waste: The sprue (excess material from the injection molding process) was difficult to recycle effectively. The manufacturer consistently achieved a recycling rate of less than 5%, a stark figure that pointed to significant material wastage.
- Increased Production Costs: Many batches of product were entirely non-recyclable, leading to direct material losses and soaring production costs.
- Quality Concerns: The final products often suffered from defects, as evidenced by “burnt” sprues, indicating poor thermal stability of the raw material.
The company urgently needed a solution to enhance the quality of their PVC compounds and refine their production processes to boost recycling rates, cut costs, and save materials.
The Solution: Green PVC’s High-Performance NHCF0857 PVC Compound
Green PVC introduced its custom-developed PVC Compound, product code NHCF0857, specifically engineered for fitting applications. This was more than just a material supply; it was a comprehensive solution that combined a superior product with expert technical guidance.
Product Features & Technical Specifications:
The NHCF0857 PVC compound offered a suite of features designed for high-quality finished products:
- Superior Aesthetics: Delivers a smooth, shining surface with high gloss due to an advanced formulation.
- Cost-Effectiveness: Formulated for high performance with an optimized amount of additives.
- Production Stability: Produced on industrial lines, ensuring remarkable quality stability from lot to lot.
- International Compliance: Fully compliant with stringent global standards, including EU REACH, EU RoHS (1, 2 & 3), and NSF 14/61, ensuring product safety and market access.

| Hardness | Shore D | 79 | ASTM D2240 |
| Tensile Strength | MPa | 48.4 | IEC811-1-1 |
| Elongation at Break | % | 108.6 | IEC811-1-1 |
| Vicat Softening Point | °C | 75 | ASTM D1525 |
| Heat Stability at 190°C | mins | 55 | IEC 811-3-2 |
Implementation: A Partnership for Optimal Results
To unlock the full potential of the NHCF0857 PVC compound, Green PVC’s experts worked closely with the manufacturer, advising on precise machine settings for optimal performance:
- Injection Process: Advised to reduce injection pressure and slow down or divide the injection into multiple stages.
- Temperature Control: Set the machine heating temperature between 155-165°C, the mixing temperature at 120°C, and maintain the cooling temperature at or below 65°C.
- Machine Speed: Operate the machine at a speed of 1100-1200 rpm with an electrical current of 48-54 Amps.
This hands-on approach ensured a seamless transition and immediate quality improvements, moving from burnt, defective sprues to clean, high-quality standard sprues.
The Results: A Dramatic and Measurable Transformation
The adoption of NHCF0857 and the optimized processes yielded outstanding results that addressed all of the manufacturer’s initial challenges.
- Massive Recycling Rate Improvement: The most significant achievement was the drastic increase in recycling rates. The manufacturer saw their rate jump from a 40% baseline to an incredible 90%, virtually eliminating waste and turning excess material into a valuable resource.
- Enhanced Production Efficiency: Overall production cost-effectiveness saw a marked improvement, increasing by 3-5% to 6-9%. This boost directly reduced manufacturing costs and increased their competitive advantage.
- Cost Reduction & Quality Assurance: The combination of a higher recycling rate, optimized processes, and a superior PVC compound led to significant cost savings and unparalleled product quality.
