Non - Threaded Standoffs Allow Screws Electronic Fasteners For PC Boards
Processing & Inspection Machine List.pdf
The non-threaded standoffs allow screws to be inserted through
multiple layered boards for stacked assemblies. All fasteners from
Polestar are identical to industry standards so that they can be
fed through standard automatic insertion equipment.
Description:
Broaching-type fasteners are designed for use on printed circuit boards and on most brittle or hard materials: such as, glass laminates, epoxy or resin with paper, nylon, or canvas bases. They are also used on materials too thin or unsuitable for threading, such as acrylic and polycarbonate panels.
Since the aforementioned materials do not flow under pressure, these fasteners are designed with a knurled shank that can be pressed into a drilled hole. The shank grips the board with an interference fit by broaching its way into the panel as it is squeezed into the holes.
Hua Bao broaching fasteners can be utilized with all types of PC boards, as well as with acrylic and polycarbonate components. They install simply, quickly, and permanently for secure and reliable attachment. Their use eliminates the need for washers, lock washers, nuts, and other excess hardware.
Our broaching fasteners includes broaching nuts with permanent
threads for board mounting or component attachment; threaded or
unthreaded standoffs for stacking or spacing and flare mounted
standoffs for greater pullout performance; threaded studs for use
as solderable connectors or as permanently mounted mechanical
fasteners with external threads; all-metal standoffs featuring a
spring action to hold a PC board securely without screws or
threaded hardware; self-expanding fasteners used in plated
thru-holes in multi-layer PC Boards; and one-piece board-mount
screw assemblies with captive screws for easy mounting and removal
of PC boards.

Q1: What is core and cavity insert?
A: The core and cavity are the two halves of the mold where the hot molten plastic material is injected into the core and cavity and the gap between the core and cavity is filled with the hot molten material during the injection molding process and then hardened into the final shape.
Q2: Why core is used in mold cavity?
A: A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece.
Q3: What are inserts in injection molding?
A: Insert injection molding is the process of molding or forming plastic parts around other, non-plastic parts, or inserts. The inserted component is most commonly a simple object, such as a thread or rod, but in some cases, inserts can be as complex as a battery or motor.
Q4: What is the difference between core and cavity?
A: The core is the male part which forms the internal shape of molding. The cavity is the female part which forms external shape of molding.
Q5: What are the different types of cooling cavity inserts?
A: Injection Molding Cooling Types and Layout:
1. Cooling line in core /cavity inserts.
2. Connecting cooling line between mold plates and inserts.
3. Different cooling line type.
4. Cooling tower.
5. Cooling line in lifter.
6. Cooling line in slider.
