The hardware-free and patented cam lock design of the NEW 500 Series from Guill means no time is wasted unbolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is required to loosen and automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the deflector, there are no material hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover.

The NEW 500 Series also features the latest Center-Stage concentricity adjustment system that significantly reduces pressure on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple replacement of locked or damaged adjusting bolts, which further saves on repair and downtime.

Another innovative feature of this new rubber/silicone crosshead is a cast aluminum liquid-fed cooling sleeve that allows the user to switch out the cooling jacket in the event of a line obstruction, again reducing downtime compared to traditional integrated cooling systems.

The NEW 500 Series crosshead with MAGS gum space adjustment is a drop-in replacement on most existing NRM lines, however this crosshead design can also be adapted to fit any extruder design or line layout.

The addition of a newly designed flow inlet channel reduces the shear and heat that is generated as the materials are being processed. This leads to lower head pressures allowing the material to move through the head in a much more balanced and even flow.

All crossheads supplied by Guill are furnished with a tool kit for assembly and disassembly as well as a detailed operator’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the NEW 500 series crosshead.

Arnold Umformtechnik GmbH & Co. KG developed the Powertite fastener to cope with such situations − a round self-tapping screw with a trilobular tapping zone. In other words where the forming work is taking place, the screw has a slightly triangular cross section (with rounded edges) to reduce the tapping torque. At a length of 3 x p (p=pitch) the tapping zone is optimized, allowing the forming work during the tapping process to be distributed over several thread flights, and ensuring that the screw is optimally set and centered.  The round load cross-section has a defined overlap; the external diameter of the screw is always greater than the nominal dimension. This enables a greater overlap on the thread flanks of the screw and of the tapped nut thread. By combining this trilobular shape in the tapping zone, and the round cross-section in the bearing zone, we achieve a significant improvement in thread-tapping screw fastenings, because, on one hand, the tapping torques are low, and on the other, the overturn torques and load-bearing capacity of the tapped nut thread are greatly increased.

It is possible to create a computerized preliminary design for a specific application using the Fast Designer Metals tool. Here, Arnold Umformtechnik always makes a recommendation for a suitable core hole layout .

 Huge savings potential possible

There are many examples of ways in which thread tapping Powertite can be used. They are applications, for example, where there is a need to implement maximum clamping forces with over-elastic assembly. And the Powertite is also suitable for component assemblies where the screw-in depth is low, yet high hole tolerances are necessary. And in many cases, it is possible to reduce weight by reducing the length of the screw and optimizing the weight of the screw heads.

The Arnold Powertite screw is a round thread-forming screw with a polygonal tapping tip and a trilobular tapping zone. The round load cross-section has a defined overlap. 

With the thread tapping Powertite the load capacity of the tapped nut thread was raised by over 20 per cent compared with standard trilobular screws. That brings with it a host of technical benefits: standards-compliant tapping torques, over-elastic assembly, including into conical cast core holes in GD-Al, pre-clamp load level similar to metric screw fastenings and the possibility of greater core hole tolerances to optimize the casting process in lightweight metals. Added to this is Powertite´s excellent assembly reliability and the fact that it can be used in steel, as well as aluminum and other lightweight metals. Moreover, it is possible to carry out repeat fastenings, and when service is required, the fasteners can be replaced by metric screws.

Applications for Powertite focus on the electromobility sector. This is particularly true for lightweight metal screw fastenings, but also when combined with cast components.The product, which has already been patented, will be launched on the market in October. 

Potential customers will have their accustomed access to the complex knowledge of the product acquired by the fastenings manufacturer, based in Forchtenberg, and also to its comprehensive understanding of the product´s performance in the various applications and sectors. All that is enhanced by the relevant calculation tool and wide-ranging  experience and expertise in manufacturing. Together with development partners in the tool-making sector, Arnold Umformtechnik has developed a completely new production process, especially for Powertite. 

The retractable feature allows the shank to retract and slide on the base without interference from the fastener. The fasteners are mounted to the fixture and the receptacle is mounted to the base. They are available in standard and heavy-duty sizes and come in various styles. As the fastener is inserted into the receptacle, the pins on the fastener align with the grooves in the receptacle. Turning the knob, which is available in either stainless steel or plastic, one quarter turn aligns and locks the fastener into place.

Retractable fasteners provide positive locking in quick change applications where there is frequent disassembly of a fixture and allow for consistent fastening force eliminating the chance for under or over tightening by the operator. They are designed to be used with cam receptacles—either embedded mount or thin-plate mount. Retractable fasteners provide changeover solutions to packaging, food processing, printing machines or assembly and checking fixtures just to name a few. The fasteners are marked with “on” and “off” indicators to show the position of the fastening pins. The bodies and shanks are made from 1045 carbon steel with an electroless nickel plated finish, or 303 stainless steel. The pins are made from 304 stainless steel.

Retractable fasteners are for use with plate thickness of 6-14 mm with up to M3 x 0.40 – Depth 3 thread or for heavy-duty plate thickness of 6-20 mm with M3 x 0.50 – Depth 6. A spacer is available to accommodate plate thickness down to 3 mm. The heavy-duty version comes in a regular sized body, also comes in a narrow-body style. Clamping force is 60N and 90N on the standard clamp and 250N and 400N for the heavy-duty version.

Quick release fasteners/clamps help increase productivity by reducing set up times, eliminating errors in assembly and installation and simplifying procedures. They are ideal for

frequent set ups regularly or to reconfigure production equipment. These fasteners may be used in automation to attach conveyors, star wheels, guide plates, pushers, handling machine chucks, rotary blades and maintenance covers on machines, to name just a few applications.

In addition to retractable fasteners, Fixtureworks also offers adjustable torque handles and knobs, myriad workholding components and fixturing accessories including workholding supports, pneumatic flex actuator clamps, nutrunner clamps, quick change pneumatic clamping fasteners, quick action sliding locks spring plunger clamps as well as handles and levers, knobs and grips, equipment handles, hand wheels and cranks, hinges and latches, leveling supports, industrial rubber bumpers, stops and wheels, fixture clamps, clamping locating systems, work positioning elements, vises, grippers and mechanical linear actuators.

The adjustable torque handles are ideal for use in fixtures and jigs requiring clamping and torque forces where full handle rotation is restricted by workpiece or limited because of fixture elements and construction. They allow the user to set a specified torque to prevent over-tightening and are ideal for applications where a consistent force is required or where over-tightening can cause damage.

The handle clicks when the specified torque, between 1-8 Nm, is reached. The locking mechanism has 12 teeth, and the amount of torque is set by adjusting the screw in the handle. The handles come with an internal tap or threaded stud. A bolt can be passed through the tapped version to secure the handle. The handle is made from 4140 quenched and tempered steel with a black or orange finish. The ratchet is made from 4115 carburized steel with a black oxide finish. The handles come in lengths of up to 90 mm and heights of 57 mm. The height extends to 63 mm prior to torquing. They come as steel handle with internal threads or steel handle with studs with threads from M6 x 1.00 to M10 x 1.50.

The torque limiting knobs both in female and male versions have two preset torque options, either 2Nm or 3Nm. They allow the user to set the specified torque to prevent over-tightening. The spring and the balls inside provide the feel and sound of a click when the specified torque is reached at the tightening end. They come in either steel with stud or tapped with steel insert, M5 x 0.80 to M6 x 1.00 thread. The overall width of the knobs is 48 mm with torque rated up to 3 Nm and tightening force up to 2.5 kN. The knobs are made from polyamide with a black or orange matte finish. The insert is made from nickel-plated 1045 steel. The stud is made from nickel-plated 1045 steel.

In addition to the adjustable torque handles and knobs, Fixtureworks also offers myriad workholding components and fixturing accessories including workholding supports, pneumatic flex actuator clamps, nutrunner clamps, quick change pneumatic clamping fasteners, quick action sliding locks spring plunger clamps as well as handles and levers, knobs and grips, equipment handles, hand wheels and cranks, hinges and latches, leveling supports, industrial rubber bumpers, stops and wheels, fixture clamps, clamping locating systems, work positioning elements, vises, grippers and mechanical linear actuators.
