Plastic assemblies - Import export

SPIROL's Series LP500 Latch Pins for Plastics are designed with a barb located under the head with a barb length equal to the width of the outermost section of the assembly. The remaining length of the LP500 Latch Pin is smooth without any other retention features. This allows the LP500 Latch Pin for Plastic to easily align and freely install through all of the holes with a plastic assembly until the barb makes contact with the final hole to securely lock the pin in place. Once fully installed, the handle will pivot freely around the non-barbed end of the stationary pin. The head prevents the LP500 Latch Pin from being over-installed, and enables the pin to be mechanically oriented for automatic installation. Manufactured from lightweight, lead free aluminium, SPIROL's LP500 Latch Pins for Plastics are available in three standard diameters: 3mm, 4mm and 5mm.

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.

SPIROL offers robust, vertical installation machines specifically designed to post-mould install Compression Limiters into a variety of plastic assemblies. The machines can install a single Compression Limiter or multiple Compression Limiters simultaneously into various polymers, thermoplastics and thermosets. SPIROL’s Compression Limiter Installation Machines are versatile solutions designed to be retooled to accommodate changing part configurations. All designs incorporate standardized machine components to reduce factory lead time, improve component reliability, and lower component costs. SPIROL also specializes in application-specific fixtures to ensure that all assembly components are held accurately in place through the installation process.

Some of SPIROL's standard Pin Installation Models can be equipped with a pusher punch (in place of a pin insertion quill) to press Threaded Inserts into plastic assemblies. The most appropriate Installation Machine depends on the actual insertion force required to press the Insert into the plastic hole and the desired productivity. Generally speaking, the Model PMH Heavy Duty Installation Machine is typically used for low to medium volume installation, and for medium to high volume installation, SPIROL's Model PH/PHX Platen-Style Installation Machines can be used for simultaneous installation of several Press-In Inserts at the same or different elevations. Due to the length to diameter ratio of Press -In Inserts, it is not possible to cost-effectively tube feed this type of Threaded Insert with SPIROL's automatic feeding and Installation machines.

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.

Sliding coating of materials of all kinds, such as metals, glass, ceramic, wood, leather and plastics As lubricant for threads of all kinds, such as machine screws, thread-cutting screws, sheet-metal and wood screws for increasing pre-tension forces or reducing screw-in torques As dry lubricant for maintenance and care of plastic/metal sliding pairs For assembly of axial face seals or dry lubrication in textile or paper-processing machines Advantages and benefits Highly effective due to outstanding film-forming properties Broad range of uses for dry lubrication in maintenance and care Waterproof and resistant to weathering

The Series 500 Extra Light Duty Coiled Pins were specifically designed for use in soft or fragile materials. The 1½ coil formation ensures that the radial force exerted against the hole wall does not exceed the strength of the hole material to prevent deformation. These pins are also an economical solution where pin strength is not a major design consideration. Typical applications for Series 500 Extra Light Duty Pins include: hinge pins in plastic or ceramic assemblies, alignment pins, and fastening applications where the hole is close to an edge of an assembly component.

Silicone-free alternative for the lubrication of O-rings and sealings during assembly. Lubrication of plastic parts such as gears, sliding surfaces, etc. Advantages and benefits Excellent adhesion on plastics and metals Tasteless and odourless Consistent properties without drying out, hardening or bleeding NSF H1 registered Compatible with plastics (see table) MOSH/MOAH-free Silicone-free
