In-house Production
- What are the delivery times for the balls you manufacture?
We aim to keep our basic range of balls in stock in sufficient quantities. If the balls you require are in stock, we can deliver them within 2–3 days. Custom production usually takes a few weeks. Ground balls are more often produced after an order.
- What parameters do I need to provide for a smooth order process?
The required parameters for the balls include:
- Glass type (material) and its properties
- Ball size (diameter)
- Diameter tolerance
- Surface specification
- Roundness specification (deviations from a perfect sphere)
If possible, it helps us greatly to know the intended application of the requested balls.
- What certificates can be provided with the delivered balls?
Upon request, we provide the following certificates with the delivered balls:
- Measurement certificate in accordance with AQL procedures. All measurements are performed using instruments calibrated by the Czech Metrology Institute.
- Document specifying the composition and properties of the glass according to the relevant ČSN ISO standard.
- Upon customer request, we are able to implement and monitor custom measuring and control procedures. We are accustomed to conducting customer audits in our production process.
Sigmund Lindner
- Is it possible to order the complete range of technical balls and glitters from Sigmund Lindner?
Yes, it is possible. If necessary, we can arrange for a specialist from Sigmund Lindner to visit the customer and assist directly on-site with the use of technical balls or glitters. - Do you supply Sigmund Lindner products from a warehouse in the Czech Republic?
No, the goods are supplied directly from a warehouse in Germany, where the entire range is available. As the warehouse is located approximately 40 km from the border, deliveries are typically very fast.
Kugler-Colors
- What is the minimum order quantity for KC products?
The minimum order quantity is:
Rods – 1 rod per color (approx. 0.5 kg)
Powders and granules – 1 kg per color and grain size - What are the delivery times for KC products?
If the goods are in stock in the Czech Republic, delivery takes 2–3 days. If it needs to be brought from the manufacturer in Germany, it can take up to 14 days, unless it is a special color made according to the customer’s specification. For rods, we keep at least two per color in stock in the Czech Republic.
- Is it possible to see samples of the individual colors?
Yes, it is. We either have a catalog with blowout shards (“plaucny”) or you can view sampler of pulled samples (30–35 g of color per 9×8 cm cup).
If you would like to see the samples, please contact us to arrange a viewing. All samples are permanently displayed at our site in Loděnice. - What is the base glass expansion for which KC rods and granules are suitable?
Rods and granules are generally prepared for a base glass expansion of 93 ± 2 x 10-7/K. However, we recommend that customers carry out a dilatation test before using KC rods or granules.
