Optimum surface cleaning with KAMAT high-pressure rotating nozzles In order to ensure a surface treatment with excellent results and within a reasonable time, we have developed special externally driven rotating nozzles suitable for our high pressure pumps: Depending on the customer's requirements, our nozzles can be driven pneumatically, electrically or hydraulically. With traditional, self-powered rotating nozzles, the water jet hits an angle before it exits the nozzle, causing the nozzle to rotate. Driving the rotating nozzle causes the water jet to lose energy and is therefore much less efficient. Our externally driven rotary nozzles concentrate the hydraulic energy entirely on the machining process. KAMAT rotating nozzles provide coherent jets that can be moved precisely and quickly over large areas. In the case of externally driven rotation, the hydraulic energy is used entirely on the surface being sprayed, giving excellent and efficient results on surfaces.

The Freek heat transfer nozzle heater type especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our patent pending Freek heat transfer alternative is brass, with or without coating, basically with a slit. Characteristics of our HotMicroCoil nozzle heaters sheathed by a reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the heater allows a very good heat transmission to the nozzle. In all our HotMicroCoils with reflection tube the assembly of a thermocouple is possible and recommended for bigger diameters and power. Also most common nozzle heater solutions are HotMicrocoil heating elements with clamp bands with diverse locking mechanisms.

The Freek-MicroCoil 1.3 x 2.3 mm used in the "Brazed-Together" energy-saving nozzle heater is wound tightly onto a precision tube with good thermal conductivity and encapsulated and thermally insulated by means of an outer housing. For even more reliable heat transfer, the heater can optionally be vacuum brazed. The "Brazed Together" design combines many advantages: high accuracy, good heat conduction, high power density, mechanical stability and, last but not least, up to 20% higher energy efficiency. Freek is one of the technology leaders in the field of hot runner heating and supplies the who's who of the industry. Energy efficiency is one, if not the central innovation topic here. Manufacturers of high-cavity PET hotrunners and moulds in particular benefit from the BT nozzle heaters, and in several ways: because the less energy that is put into the system, the less energy has to be taken out on the cold side, the mould. This saves even more energy and shortens the cycle time.

Our Locking System provides a quick, easy and reliable clamping of the heating element on the nozzle to be heated. It facilitates an effective heat transfer, as the inside sheath is pressed to the nozzle with a high level of precision creating an interference fit. Due to the method of construction of the lock, installation is possible in the restrictive space of small cavities. The lock can be operated quickly and efficiently with simple readily available tools.

Especially for high-cavity PET plastic injection moulding there are various industry standards of clamp-band nozzle heaters available. Most common are the Axial Clamp-Band Heater and the Two-screw Clamp-Band Heater. Our HotCoil cable heaters with clamp band represent a highly demanded and very flexible clamping system, especially for heating larger nozzles and bushings with high power. The size-variable customizable clamp bands counteract the heating's thermal-related "lifting ambition" during heat-up and thus effectively prevent a possible critical overheating. For an even better protection all HotCoil heating elements can also be provided with an integrated thermocouple. As alternative to our standard clamping mechanism with welded clamping elements a space-saving lug clamping mechanism can be supplied.

The Freek heat transfer nozzle heating system especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our Freek heat transfer nozzle heater alternative is brass, with or without coating, preferably with a slit. The slit allows the assembly of an external bendable thermocouple and facilitates the disassembly, e.g. in case of a revision and can be coiled over. This is not possible at competitor's nozzle heater solutions. Freek's tight coiling at the heater's ends provides a maximum possible power concentration (patented).

EZM Driveline – This is the brand name under which EZM can supply you with drawn bright steel, ground bright steel, peeled bright steel and ground-and-polished bright steel in virtually all cold-formable alloyed and carbon steel grades. Our bright steel is characterised by great dimensional accuracy and high-quality, bright surfaces. Compared to rolled and forged products, cold-drawn bright steel offers the advantage of a greater range of processing options. Of very special importance in this context is a lead-alloyed carbon steel for diesel injection pumps. The unique properties of this EZM speciality offer the perfect answer to such contradictory demands as maximum pressure resistance, on the one hand, and optimum machining properties, on the other. EZM is also a specialist for the processing of antifriction bearing steel/ball bearing steel, as well as alloyed high-grade structural steel.

Owing to their small cross-sectional dimensions, MicroCoils are most often connected at both ends and do not permit the addition of a thermocouple. We prefer to use nickel as the sheath material here because it combines the best thermal conduction properties, high corrosion resistance and excellent deformation properties. To ensure that the standard 1000 mm PTFE-insulated connection cable can be positioned at one end, despite the standard two-ended connection of the element, in most cases the MicroCoil is formed into a hairpin shape and wound/laid in a bifilar (parallel) format. Our unformed MicroCoils are also supplied in the hairpin bend shape as standard.

The nozzle consists of two counter-rotating nozzle housings into which the nozzle tubes are inserted with a connection for screw-in round jet nozzles. A special packing sealing system inside the nozzle housings ensures protection during operation and prevents the ingress of contaminants. In front of and behind the nozzle housings are spacers (basket system) to prevent the nozzle tubes from hitting the well wall. In addition, for best cleaning results, the temperature of the medium should be between 3 and 30°C.
