Pin Installation Technology

SPIROL Pin Inserters feed all common types of pins — headed or straight — as well as bushings, rivets, compression limiters, and many other similar components.

Whether your requirements are for a standard pin inserter with or without fixturing or a custom designed system, our objective is to build reliable and cost effective equipment that provides the right degree of automation based on the volume and complexity of the assembly process involved; the degree of automation that yields the lowest per unit assembly cost and the optimum pay back.

We offer:

  • Pin Driving Chucks
  • Manual, semi-automatic, and automatic machines
  • Simultaneous multiple insertions
  • Vertical and horizontal styles
  • Error-proofing options such as custom fixturing, pin sensing, force monitoring, drilling and pinning combinations, etc.

Manual Pin Inserters and Pin Driving Chucks provide sturdy, economical installation methods for low-volume work and prototype designs.  Manual inserters require that the fastener be manually loaded into the part or the machine.  The operator then completes the installation by depressing the arbor press lever.

Automatic Inserters are completely self-contained.  The fastener is oriented in a vibratory feeder and fed to a shuttle mechanism that positions the fastener directly underneath the insertion quill.  The shuttle is mounted on a retracting mechanism that positions the shuttle as close to the part as possible for insertion, yet out of the way for loading and unloading.

Vertical Pin Inserters are available in a wide range of sizes matched to pin lengths and insertion force requirements.  Standard machines capable of simultaneous multiple insertions are available.

Horizontal Pin Inserters for single or multiple installations feature rotary shuttles for reliable pin orientation.

model pm
Model PM Manual Pin Inserter
This exceptionally versatile tool is ideally suited to all levels of production: from a single unit for prototype assembly, to multiple units on an assembly line. The Model PM easily accommodates quick change-overs. The part holding device (fixture) is simply replaced from the base of the machine. The pin diameter is easily changed, positive pin depth easily adjusted, and part size variation easily accommodated. The use of high-tech shafting and bearings results in smooth operation, precise positioning, repeatability, and durability.

The Model PM Manual Pin Inserter installs pins ranging in diameter from 0.8mm-4mm (.031”-.156”) with a maximum insertion force of 0.9 kN (200 lbs).

model pmh
Model PMH Heavy Duty Manual Pin Inserter
This exceptionally versatile tool is ideally suited for low to moderate levels of production: from a single unit for prototype assembly, to multiple units on an assembly line. The Model PMH easily accommodates quick change-overs. The fixture is simply replaced at the base of the machine, and the pin diameter is easily changed by switching the pin driving chuck. The precisely machined rack and casting results in smooth operation, precise positioning, repeatability, and durability.

The Model PMH Heavy Duty Manual Pin Inserter installs pins ranging in diameter from 0.8mm-10mm (.031”-.375”) with a maximum insertion force of 6.7 kN (1,500 lbs).

model pmx
Model PMX Extra Heavy Duty Manual Pin Inserter
This versatile tool is ideally suited for low to moderate levels of production for assemblies that require installation forces up to 26.6 kN (6,000 lbs). The Model PMX Extra Heavy Duty Manual Pin Inserter easily accommodates quick change-overs. The fixture is simply replaced at the base of the machine, and the pin diameter is easily changed by switching the pin driving chuck. This Extra Heavy Duty Manual Pin Inserter will provide smooth operation, repeatability and durability.
model pr
Models PR Semi-Automatic Pin Inserter
This exceptionally versatile, vertical installation machine is ideally suited for moderate to high production for applications requiring up to 1.3 kN (300 lbs) of installation force. A retractable pin insertion head, mounted on a shaft/linear bearing arrangement, moves up and down for ease of loading and unloading of the components to be assembled. The machine’s insertion bushing is positioned close to the part for smooth, trouble free installation.
model cr
Model CR Semi-Automatic Heavy Duty Pin Inserter
This robust, vertical pin insertion machine is ideally suited for moderate to high production for applications requiring up to 8kN (1,800 lbs) of installation force. A retractable pin orientation head, mounted on a shaft/linear bearing arrangement moves up and down for ease of loading and unloading of the components to be assembled. The insertion bushing is positioned close to the part for smooth, trouble free installation.
model crd
Model CRD Semi-Automatic Dual Pin Inserter
Whenever simultaneous multiple-pin insertion is feasible and practical, it should be considered to enhance productivity. This robust, dual vertical pin insertion machine is based on SPIROL’s standard Model CR design. Able to install two pins simultaneously, it is ideally suited for moderate to high production for applications requiring up to 8kn (1,800 lbs) (2 pin total) of installation force. A single dual or twin single (based on the center distance needed) retractable pin orientation head, mounted on a shaft/linear bearing arrangement moves up and down for ease of loading and unloading of the assembly components. The installation bushings are positioned close to the parts for smooth, trouble free installation. The orientation head shuttles the pins from the feeding position to the installation position and functions as a selector, preventing longer or shorter pins from being installed. A two position trap door allows easy clear-out of the feed tube without the need for tools.
model hc
This lightweight, portable, horizontal Pin Inserter is designed to install SPIROL Series 550 Cosmetic Coiled Pins into plastic hinges. The cylinder/driving head modules can be moved in and out with ease, and fixture changes are simple which enables quick conversion from one assembly to another. This machine quickly and effectively delivers the pins automatically to the installation site eliminating the need for the operator to touch them during the entire assembly operation. This machine dramatically increases production efficiency with minimal operator training and effort.
model sg
Model SG Semi-Automatic Dual Pin Inserter
Geared to the Safety Glasses industry, this time tested, proven reliable machine installs a self-locking pin developed by SPIROL into the assembly. This innovative pin, called the Twist-Lok™ Pin, replaces commonly used threaded screws as the hinge pins in the temples of the glasses. Screws are generally known to be more expensive, difficult to install, and subject to working their way out of the holes. SPIROL® Twist-Lok™ Pins are simply pressed into the holes, and they create a tight hinge connection that will not work itself loose over time.
model dp
Model DP Drilling & Pinning Machine
This self contained vertical drilling and pinning machine is ideally suited for moderate to high production applications that require accurate drilling and pinning of assemblies. The concept of drilling and pinning with one system eliminates tight tolerance and precision drilling of individual components to ensure proper alignment of holes for assembly. The Model DP Drilling & Pinning Machine consists of an automatic high-precision drilling unit, a SPIROL Model CR Pin Insertion Machine and a precision air-powered linear slide unit to move the assembly between the drill unit and installation station.

The Model DP Drilling and Pinning machine can drill holes ranging in diameter from 0.8mm-6mm (.031”-.250”) and is capable of insertion forces up to 8 kN (1,800 lbs).

pin driving chucks
Pin Driving Chucks
SPIROL offers a line of light duty and heavy duty Pin Driving Chucks designed to be used in SPIROL’s Manual Pin Inserters (Model PM, Model PMH or Model PMX). The Pin Driving Chucks may also be used in a drill press or arbor press with an adaptor. All models are designed with spring tension at the tip to hold the pin securely in place prior to and during installation. The exposed end of the pin is then placed into the hole and the tool is advanced to complete the installation. The tools are supplied with a flush, above-flush or below-flush setting, depending on the application requirements.
