Design of moulds - Import export

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.

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.

TPE compounds for plastic closures using the in shell liner moulding process The EPSeal 800 series was developed for PE and PP closures specially designed for the in shell moulding liner technology. The series includes versions for cold fill, pasteurisation and hot fill beverage treatment systems. This series also includes versions with different rheological values to address the special processing requirements of different lining machine types. An assortment of lubricant packages addresses the spectrum of closure and liner profile designs but all lead to a neutral taste and odour sealant whilst remaining consumer friendly and reliable.
