Successful product case study: measuring stand with deep bores and oxygen-free bonding
The Challenge: Why This Measuring Cylinder Is So Complex
Since it is a true measuring tool, not only must its functionality be spot-on, but so must its readability and appearance. In practice, this means that every machining operation, every fit, and every assembly step must be perfect, because even a small deviation can directly affect measurement accuracy and reliability.
What made this PMMA measuring burette so challenging was the combination of multiple critical requirements in a single elongated product:
- Long protrusion length: Vibrations during rotation of the product had to be completely eliminated.
- Deep and precise bores: Extremely high requirements for straightness, dimensional accuracy, and repeatability.
- A valve connection that must be completely leak-proof even under pressure. This is essential for reliable operation and safe use, since the burettes are used with lye solutions up to 30% concentration.
- Engraving in combination with precision bores: the scale must correspond exactly to the actual volume.
- Visually visible component: sleek appearance, perfect readability, and sufficient contrast in the inner bore.
A product where precision is key
This measuring cylinder requires an exceptionally high level of precision and reliability. To ensure the required performance in terms of capacity, accuracy, and liquid-tightness, extensive quality verifications were conducted in the past. It is precisely these high quality standards that make the product a fine example of technical complexity and craftsmanship in plastics processing
That is why it was important to have a partner who understood the big picture and possessed the necessary expertise. While many companies viewed this as a risk, we at BKB Precision saw it as a challenge we were eager to take on.
Our approach at BKB: first, we listen and collaborate; then, we produce
At BKB Precision, we don’t start these kinds of complex projects right at the machine; we start them around the table. During a kick-off meeting with our technology team and the customer, we went through the product step by step. We actively contributed ideas and provided advice on manufacturability, reliability, and the critical points within the process. By identifying risks early on, we were able to focus our efforts on achieving a stable and reproducible solution.
We then assembled the right internal team to manage this project from start to finish. A production engineer and a sales engineer served as the link between the client’s requirements and implementation, supported by an experienced machinist for precision machining and a craft specialist with expertise in complex bonding. Thanks to this mix of disciplines, we knew exactly where the pitfalls lay and, most importantly, how to avoid them.
With all that knowledge and experience at the table, we then translated the process into control and certainty. A clear workflow emerged, with well-defined process steps and corresponding work instructions. This minimized surprises and kept the focus on a single goal from the start: a measuring stand that is not only technically sound but can also be produced reliably and consistently.
The Final Result
The result is a measuring burette that meets Pentair Haffmans’ high quality standards in all crucial aspects. Thanks to a well-thought-out engineering approach, optimal manufacturability, and rigorous quality assurance, we have created a product with consistent measurement accuracy, excellent fluid tightness, and reliable performance under pressure. The burette also meets high aesthetic expectations, featuring a high-quality finish and optimal readability.
This project underscores the importance of collaboration, craftsmanship, and continuous improvement. The combination of Pentair Haffmans’ high-quality standards and BKB Precision’s technical expertise has led to a robust and reproducible production process, resulting in a product of which both parties can be proud.
What does the customer think?
“This measuring bench requires a high degree of precision and reliability. BKB Precision has demonstrated that it not only possesses the technical knowledge and experience, but also the right mindset to work together to find the best solution. The end result is perfectly in line with the quality standard we aim to offer our customers.”
Craftsmanship, Preparation, and Results
Complex products require more than just a good machine: they require the right people, the right preparation, and a rock-solid process. At BKB Precision, we’re passionate about products that go that extra mile.
Where others give up, we persevere with knowledge, control, and craftsmanship. Because when technical complexity and high-quality standards come together, that’s when we’re at our best.
