Bolt Machine

The Zino 24B4SLL multi stage bolt machine, four main dies and four punching dies, rated at up to 45 pieces per minute.

Product Overview

What This Innovation Product Does

The Zino 24B4SLL is a multi stage cold forming bolt machine built for power fitting and transmission hardware producers. It works with four main dies and four punching dies, takes stock up to 20 mm in diameter and produces bolts up to M16 or 5 eighths of an inch, between 100 mm and 305 mm long, at a maximum rate of 45 pieces per minute. Projects are delivered with the full die set, and in the South Asia bolt project the machine was supplied with an upsetting machine and a thread rolling machine to US ASTM practice.

Key Benefits

  • Multi stage forming in one machine instead of repeated handling
  • Full die set supplied with the machine
  • Rated capacity of up to 45 pieces per minute
  • Delivered with upsetting and thread rolling equipment when the project needs a complete bolt line

Problems It Solves

  • Single stage machines cap output and multiply handling
  • Die sets bought apart from the machine rarely match it
  • US standard requirements are hard to verify before the line is built

Application Scenarios

  • Bolt line for transmission tower and power fitting hardware
  • Fastener plant serving a national grid programme
  • Existing forging shop moving to dedicated bolt production

Who It Is For

  • Power fitting manufacturers
  • Bolt and fastener producers
  • Investors localising transmission hardware supply

Technical Features

  • Four module multi stage forming
  • Separate cutting, main and punching die sets
  • 190 ton compressive strength
  • 100 HP main motor with a 4 HP lubricating oil motor

Comparison

How It Compares

Power Fittings lineThe bolt machine is the forming heart of a fastener plant, while the power fitting line covers the wider hardware range around it.
Single stage bolt headerFour modules let one machine complete several forming stages, which is where the 45 pieces per minute rating comes from.
Use Guide

How A Project Runs From Enquiry To Production

  1. Send the bolt drawings, sizes and annual volume
  2. Zino specifies the machine, the die set and any supporting machines
  3. Installation, debugging, trial production and training follow delivery
FAQ

Bolt Machine Questions

What is the largest bolt the machine makes?
The maximum production specification is M16 or 5/8 inch, with lengths from 100 mm to 305 mm.
How much floor area does it need?
The machine occupies 8060 mm by 3620 mm and weighs 60000 kg, so the foundation must be planned before delivery.
Can it be supplied to US standards?
Yes. The South Asia bolt turnkey project was executed to US ASTM standard, including the full die set.
What output can we expect per year?
The South Asia project produces 6 million bolts of different sizes per year.
