Master Unit Die's Enhanced Series Mold Inserts Feature Multi-Purpose Post

New Master Unit Die (MUD) Enhanced Series Mold Inserts optimize moldmaking efficiency for users of quick-change interchangeable mold insert systems, including the MUD quick-change system.

The new mold inserts feature a streamlined ejection system with solid post-style design. This configuration maximizes available insert core and cavity surface area, provides more room for thicker pocket walls, and offers additional clamping surface area for faster, easier machining setup. 

Enhanced Series Mold Inserts are compatible with the MUD Quick-Change System (QCS) U Frame to provide a flexible solution to higher productivity and lower mold tooling costs.

A multi-purpose post guides ejection, retains the ejection system, and provides support without the need of additional support pillars. Enhanced Series Mold Inserts come installed with four leader pins and bushings, four return pins, and eyebolt holes. A tapped hole is provided for insert installation/removal. Parting line plates are finish ground, and ejector plates are bolted together for maximum convenience. 

Available in the 08/09 Series, MUD Enhanced Series Mold Inserts are offered in D-M-E #2- and #3-type steels. Ejector plates are available in an optional 0.480-inch thickness. 

Enhanced Series Mold Inserts have the same fast delivery as all MUD quick-change system products, typically less than one week.

Master Unit Die, a D-M-E company, developed its concept for Quick-Change over 40 years ago to meet the parallel challenges of increasing productivity and decreasing cost. This tooling approach to injection molding offers mold makers and plastic manufacturers a number of competitive advantages. These include lower tool costs and faster production changeovers, ideal for just-in-time scheduling.

MUD Quick-Change Systems use standard mold base frames that remain fixed in the injection molding machine. The easily manufactured mold inserts can be quickly changed, making the system ideal for short production runs of multiple parts. Mold makers need only construct the core, cavity and ejection portions of the mold, which can reduce mold construction costs by as much as 65%. This approach also offers mold makers and molders the competitive advantages of quicker mold delivery, faster initial setup, faster production changeovers, minimum purging, and easy maintenance and repair.

In production, MUD quick-change systems provide advantages for molders. The primary benefit is rapid mold change. Set-up of the mold is reduced to installing the parts, clamping them to the frame, and connecting the cooling/heating lines. This usually takes five minutes or less, and can result in a 75% saving in set-up time, enabling short, efficient production runs in JIT operations. Maintenance and storage of the mold is also easier, given the lighter weight of the insert set compared to an entire mold.
