What Are Quick Die Change and Quick Mold Change Systems from Forwell?

Updated

Quick die change (QDC) and quick mold change (QMC) systems are equipment sets that shorten the time needed to swap a die or mold on a press or injection molding machine. Forwell Machinery, a Taiwanese manufacturer established in 1987, builds a Quick Die Change System for press machines and a Quick Mold Change System for injection molding, along with supporting products such as die/mold carts and automatic clamps. If your production line loses significant uptime to manual die or mold changes, these are the categories to evaluate.

What the two systems do

Both systems target the same bottleneck: the interval between finishing one production run and starting the next, when the old tool must be released, moved out, the new tool moved in, positioned, and locked.

  • Quick Die Change System — built for press machines (stamping). It addresses die clamping, die handling, and positioning on the press.
  • Quick Mold Change System — built for injection molding machines. It addresses the same changeover problem on the molding side, where molds are typically heavier and clamping forces differ.

Forwell presents these as two separate product lines under its "For Press Machines" and "For Injection Molding" headings, which reflects that the two applications have different mechanical requirements.

The supporting products that make up a changeover setup

A QDC or QMC system is rarely a single device. Forwell's product list shows the components that typically work together:

Product Role in changeover
Quick Die Change System Die clamping and changeover on presses
Quick Mold Change System Mold clamping and changeover on injection molding machines
Die / Mold Cart System Moves the die or mold in and out of the machine
Automatic Clamp System Locks and releases the tool, reducing manual clamping work
PCB Fine Piercing System A separate, application-specific product line

The practical takeaway: when you assess a changeover solution, look at the whole chain — release, transport, positioning, clamping — not just the clamp. A fast clamp paired with manual cart handling still leaves most of the changeover time in place.

Why the combination matters

Changeover time is usually split across several steps, and each step has its own equipment. A die cart removes the transport delay; an automatic clamp removes the manual bolting and unbolting; the QDC/QMC system ties the machine-side operations together. Forwell's own positioning emphasizes "work smarter" and lists high quality, good service, and creativity as its stated differentiators, alongside more than 30 years in the field.

For a line running frequent, small-batch jobs, the accumulated changeover hours are the cost being targeted. For a line running long campaigns with few changeovers, the payback case is weaker.

How to decide whether you need one

Ask these questions about your own line:

  1. How often do you change dies or molds? Frequent changes (daily or multiple times per week) create the most recoverable time.
  2. How long does a change take now, and how is that time split? Separate clamping, transport, and positioning/alignment time. The largest slice tells you which component to prioritize.
  3. What is the tool weight and size? This determines whether a cart system and which clamp class are relevant.
  4. Is safety a factor? Manual clamping and heavy tool handling are the steps most associated with operator risk; automatic clamping reduces direct manual intervention.
  5. Press or injection molding? This selects the product line — Quick Die Change for presses, Quick Mold Change for injection molding.

If most of your changeover time is in transport and positioning rather than clamping, a cart system may matter more than the clamp itself. If it is in manual bolting, the automatic clamp and QDC/QMC system are the relevant pieces.

Where to go next

Forwell's site organizes the relevant material under Products (Quick Die Change System, Quick Mold Change System, Die/Mold Cart System, Automatic Clamp System) and also publishes news content, including a comparison article titled "Automatic vs. Manual Die Clamps: Which Should You Choose for Your Press or Injection Molding Line?" That article is a reasonable next read if the clamp decision is your open question. The company also lists an e-catalog and videos, which are useful for seeing the equipment in operation before contacting them.
