Flexible, versatile solutions for post-mold Insert installation into thermoplastic and thermoset plastics. SPIROL's Installation Machines are the ideal foundation for stand-alone systems and enhanced assembly systems provided by SPIROL. Our standardized, time-tested, modular designs are robust, reliable and easily adjustable — allowing simple customisation to meet the specific needs of your application. More than 80% of the components in the Insert Installation Machines we design are pre-tested and production-proven standard items. This translates into faster delivery, greater reliability, and lowest cost for Insert Installation Equipment of comparable quality. We specialize in custom application-specific part holding devices. Fixturing – holding your components accurately and firmly during insertion – is a critical element to the performance of your assembly equipment.

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.

Thread turning is a special turning process.In thread turning a distinction is made between three different forms of presentation; the use of these depends on the thread pitch, the machine tool, the work-piece material and the cutting edge geometry. In the case of large threads, the tool must traverse the same track several times, penetrating deeper each time. The full depth of cut is therefore divided into several smaller cuts, thus preventing an overload on the sensitive tip of the thread profile of the cutting edge. In order to ensure profile accuracy, the helix angle of the thread must coincide as far as possible with the angle of inclination of the threaded plate. Thread turning method
