SPIROL offers a line of austenitic stainless steel Disc Springs in diameters ranging from Ø8mm to Ø71mm. Austenitic stainless steel is typically used for static and low cycle applications that require a heightened level of corrosion resistance. It withstands fresh water and atmospheric marine conditions very well, and is suitable for many other industrial conditions including acidic environments. This material will continue to work harden with use so cycle life is limited, but creep resistance is good. SPIROL supplies both single Disc Springs as well as Pre-Stacked Disc Springs in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!

The mechanical back-up design uses SPIROL® Disc Springs. Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series. If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism. A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes. The reliability of this safety system is dependent on the consistent performance of Disc Springs. In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety. SPIROL® Disc Springs have a high capacity to consistently store releasable mechanical energy. Visit www.SPRIOL.com to learn more!

DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

SPIROL offers a line of light duty and heavy duty Pin Driving Chucks designed to be used in SPIROL’s Manual Pin Inserters (Model PM, Model PMH or Model PMX). A Pin Driving Chuck may also be used in a drill press or arbor press with an adaptor. All Pin Driving Chucks are designed with spring tension at the tip to hold the pin securely in place prior to and during installation. The exposed end of the pin is then placed into the hole and the tool is advanced to complete the installation. The tools are supplied with a flush, above-flush or below-flush setting, depending on the application requirements.

SPIROL specializes in the manufacture of precision machined AAR Nuts for the railroad industry. SPIROL's Railroad Nuts are held 100% square to the tap. SPIROL's thread pitch diameter allowances are engineered for ease of assembly after plating, yet manufactured to strict standards with specific gages. Each production lot has a unique identification number and is traceable through each manufacturing process back to the original raw material test certificate. SPIROL's Railroad Nuts, otherwise referred to as AAR Clamp Nuts, Binding Nuts, and Gold Test Nuts or AAR Signal Nuts are used in signal lights, crossing bells and terminal blocks.

Moulded-In Inserts are placed over core pins by an operator or a pick-and-place robot prior to the closure of the mould cavity during the plastic injection process. Moulded-In Inserts offer exceptional torque and pull-out resistance due to unrestricted plastic flow around the Insert body, and are often the Insert of choice for thermosets and engineered plastics with a high percentage of filler. The minor thread diameter tolerance is controlled to ensure positive positioning and perpendicularity of the Insert on the core pin during the moulding process. Series 63 is symmetrical eliminating orientation and Series 65 is the same body style in a blind ended version. SPIROL's Moulded-In Inserts are made from 2024 aluminium, a light-weight, lead-free grade. SPIROL’s Series 63 and Series 65 Moulded-In Aluminium Inserts are available in thread sizes ranging from M4 (8-32) up to M8 (5/16-18).

Heat / Ultrasonic Inserts are designed for post-mould installation in thermoplastics. Heat and ultrasonic installation yield outstanding performance results. SPIROL offers several different series of Heat/Ultrasonic Inserts available in a long and short version of each thread size. Long lengths maximize torque and pull-out resistance, while short lengths are good for less stringent requirements at lower cost and shorter installation times. Some styles are available with or without a head. The head provides bearing surface for the mating component that also prevents jack-out (or when used in reverse, can prevent pull through). However, adding a head results in additional cost raw material of a larger diameter is required to create the head. Some non-headed Inserts are symmetrical – thus eliminating the need to orient the Insert prior to installation.

The course external thread of SPIROL's Self-Tapping Insert forms an internal thread within a molded or pre-drilled hole during the installation process into a plastic assembly. SPIROL Series 10 Self-Tapping Inserts are thread forming Inserts best suited for softer thermoplastics or thermosets. Self-Tapping Inserts provide the best pull-out resistance for a post-mold installed Insert, yet generally cost more than their post-mold counterparts. The external threads are designed with a thin profile to minimize induced stress in the plastic and have a relative coarse pitch to provide the maximum plastic shear surface to resist pull-out.

Press-In Inserts are designed to be pressed into a straight hole without melting the plastic prior to installation. Ideal for use in softer plastics, the helical knurls of the Press-In Inserts are used to provide both torque and pull-out resistance and to ensure good plastic flow as the Insert rotates into the hole. Installation torque to achieve sufficient tension between the threads is not a problem in that the helical knurls are designed so that the direction of the installation torque will have the tendency to drive the Insert into the hole — which of course is not possible — as the threaded joint is tightened. A pilot only slightly smaller than the hole and of sufficient length is designed to assure straight insertion into the hole. Press-In Inserts offer rapid installation with no specialized equipment and achieve good overall joint performance. If installation equipment is required, SPIROL also offers a standard comprehensive line of Insert Installation Equipment.

SPIROL manufactures several different types of Moulded-In Compression Limiters that are designed to be installed into the plastic assembly during the moulding process. When moulding Compression Limiters into the plastic assembly, the moulding time is increased as the operator or a pick-and-place robot must load each Compression Limiter over the core pin(s) prior to closing the mould cavity. Precise placement of the Moulded-In Compression Limiter over the core pin is required; otherwise mould damage can occur. SPIROL Standard Moulded-In Compression Limiters include: The Series CL500 Moulded-In, Series CL460 Moulded-In - Oval, Series CL600 & CL601 Aluminum and Series CL800 & CL801 Brass.

A fuel injection systems manufacturer used two steel brackets to clamp the fuel rail to the top of the engine. The customer was looking at changing these brackets to plastic to reduce costs. In order to prevent deformation of the plastic bracket during the tightening of the bolt, a Compression Limiter was required. The customer originally investigated the use of a machined Compression Limiter, but the savings from changing the metal bracket to plastic would have been lost considering the high price of the machined Limiter. The customer approached SPIROL to help provide a lower cost solution for the Compression Limiter. SPIROL recommended the use of a standard CL200 Compression Limiter based on the rated proof load of the bolt used in the assembly. This roll-formed Compression Limiter is a fraction of the cost of a machined Compression Limiter. In addition, the flexibility of the roll formed Limiter enabled the customer to widen their hole tolerances further reducing assembly costs.
