The assortment also includes handles for specific purposes:
- HD – products for the food, medical technology and pharmaceutical industries with a high-quality surface and sealed bolting areas, without gaps where bacteria accumulate;
- CLEAN line – especially suitable for medical environments, as it allows the prompt identification of any dust or dirt traces, making cleaning operations easier. The compact shape and the lack of cavities prevent the accumulation of dirt and dust;
- SAN line – products avoid reproduction of undesired bacterial organisms which can cause unpleasant odours, discoloration, degradation and formation of biofilm on surfaces. Handles and knobs containing antimicrobial additives or coated with a special finishing material to offer an efficient protection against bacteria spreading. Intended for disability aids, medical and hospital equipment;
- SOFT-TOUCH – product line features a soft and slip-proof surface to ensure a safer and more stable ergonomic grip even under unfavourable conditions of use such as in the presence of moisture and grease. Moreover SOFT-TOUCH allows a better force transfer between hand and operating elements and ensures the absorption of vibrations during operations. Designed for: disability aids, high-precision instruments, fitness machines, gardening and unfavourable climatic conditions;
- Visually detectable – components are easily detected and recognized by the human eye due to their specific and unique color, which is not naturally found in the environment. Made of technopolymer “Signal blue” RAL 5005, suitable for contact with food (FDA CFR.21 and EU 10/2011). Compliance with FDA regulations allows in addition a high level of prevention against the risk of contamination of the food. Designed for food industry machinery, pharmaceutical equipment;
- Detectable by metal detector – technopolymer handles, “green blue” RAL 5001 color, suitable for contact with food (FDA CFR.21 and EU 10/2011). A special additive in the plastic material allows the detection of cubic particles of 5 mm by means of a metal detector. Compliance with FDA regulations allows in addition a high level of prevention against the risk of contamination of the food. Designed for food industry machinery, pharmaceutical equipment;
- ELECOLORS® – the use of increased colors not only provides aesthetics and compatibility, but also allows for better separation of machine functions and ensures safety;
- ERGOSTYLE® – were created for areas such as hospitals, medical, sports and leisure equipment, scientific instruments, office furniture, which, in addition to functionality, require special attention to ergonomics and design. Today, ERGOSTYLE® products benefit more and more traditional industrial sectors, machines and equipment over several decades of substantial aesthetic and design renewal.
What makes star-shaped handles superior to traditional ones?
Star-shaped handles are appreciated for their ergonomics and excellent grip. Unlike traditional round handles, the star-shaped design provides more support points, making it easier to position your hand and transmitting torque more precisely. This is especially useful when you need to adjust equipment frequently or with greater pressure. Thanks to the comfortable grip, such handles help prevent slipping and reduce hand fatigue.
How do star-shaped knobs ensure convenience and precision when adjusting equipment?
The shape of the handle allows the operator to grip it firmly and adjust the position precisely. When gentle or slow tightening is required, additional support ribs help the hand move stably. And when higher torque is required, the star shape provides natural leverage, which allows you to achieve the result without additional tools. This is especially important in industrial systems, where precise adjustments often have to be made.
Why are star-shaped handles often used in industrial systems?
In industry, reliability, safety and quick operation are paramount. Star-shaped handles are highly resistant to wear, vibration and continuous use. They are made of robust technopolymer or metal, making them suitable for both heavy and precision systems. In addition, the handles allow for quick tightening or loosening of components, even in emergency situations when the operator needs to act quickly.
When is it worth choosing star-shaped handles based on the working environment and needs?
These knobs are worth choosing when the equipment is used intensively, when frequent adjustments are required, or when operators work with gloves. For environments where moisture, grease, or dust are prevalent, knobs with a non-slip surface are best suited. For heavy loads, metal versions should be chosen. If precision is the most important thing, choose options with integrated locking.
