Inserts for Plastic Assemblies
reusable metal threads for mating hardware and allow
for repeated disassembly and re-attachment whenever
required. By promoting quick and easy access to an assembly,
SI inserts offer highly practical joining solutions
in contrast to fixed and unyielding methods, such as adhesives
or rivets. Repeated reuse will not damage the
strong metal threads or compromise attachment integrity.
Types include brass inserts and lead-free stainless
steel and aluminum versions.
Applications include plastic equipment or components
for the medical, automotive, aerospace, transportation,
and recreational industries, among many others.
All SI inserts install permanently in plastic, offer
unique features, and can be classified generally by installation
method. Depending on series, inserts can either be
ultrasonically pressed and/or heat staked, molded-in during
the injection molding process, or cold pressed into a
pre-molded or drilled hole.
SI inserts can be specified in unified or metric thread
sizes and in a variety of designs and lengths – including
SI microPEM® inserts with threads as small as M1.
