perfect pin guidance
▲
precision finished components
Perfect hardness and finish promotes gate longevity and good mechanical running characteristics
in the manifold V-GUIDE SYSTEM
The patent-pending V-Guide system utilizes a novel approach to preventing material from migrating between the valve pin and valve disk (1) by creating a thermal barrier within the valve disk itself. This seals material from flowing between the valve disk and the valve pin but is still thermally isolative from the manifold to avoid excessive heat escaping from the manifold. Combined with precise machining tolerances, this creates an efficient leak-proof seal at the interface of the manifold to the valve pin guide system.
in the gate
The Accu-Valve line of cylindrical valve systems all have specially designed bi-metallic liners that perfectly pre-align the pin through the gate area. This design does not rely on cavity steel for pin alignment, greatly reducing any risk to gate steel wear and ensuring that perfect gate quality remains after millions of shots. Also, the design eliminates stagnation of resin/color that is caused by traditional guiding devices.

• small profile nozzles to access small parts or difficult-to-reach gating surfaces
• Master-Series® nozzles
which offer the largest range of melt conveying capacity
benefits to the processor
• optimal process window for all thermoplastic resins • unsurpassed color change
performance • industry’s smallest
nozzles for thermally sensitive resins
• best gate area longevity with optimal gate quality resulting in perfect parts
applications
• polyolefin resins

the science in
valve gating
Pristine gate area cosmetics, a wide
processing window, gate steel longevity, and ease of integration are the key elements for a great valve gate system. To accomplish this, hot runners must balance precise machining tolerances, optimal gate area temperatures, and the mechanics of the valve actuation and manifold system. Whether in high cavity packaging molds or demanding medical device applications, the next generation Accu-Valve
designs answer all these challenges.

Precise valve pin manufacturing
Accu-Valve – finally a family of valve gating solutions to suit every molding need
ACCU-VALVE CX – FOR COMMODITY RESINS
TheAccu-Valve CX takes the principle of the Accu-Valve cylindrical valve gate system to a new level.
The open flow channels in the patent-pending liner design provide for accelerated melt flow and dispersion with virtually no dead or blind spots in the constant guiding mechanism. This dramatically accelerates color change versus conventional cylindrical valve gate systems, critical in high cavity packaging and personal care applications. The precise alignment of the liner and continuous engagement with the pin assures pristine and durable gate performance. Recommended for polyolefins and commodity resins where melt viscosities are relatively low and where color change and pristine gate quality is a must.
Mold-Masters also offers unique valve gating solutions for specific application needs including:
BI-METALLIC CYLINDRICAL DESIGN
for standard applications
HOT VALVE TAPERED DESIGN
recommended for engineering grade materials with fillers or reinforcements
C-VALVE TAPERED DESIGN
perfect for heavier wall section parts such as automotive lens applications and crystalline and semi-crystalline materials
▲
Perfect for high tolerance,
geometrically precise medical parts
ACCU-VALVE EX – FOR ENGINEERING RESINS
Cylindrical valve gating for engineering materials presents challenges to conventional technology due to the relatively higher temperature resins, crystalline or filled nature of the materials and subsequent resistance to pin closing.
The Accu-Valve EX design provides precise gate area thermal conditions to ensure no pin resistance to closing while still maintaining exact alignment between the pin and cavity insert. The design also ensures that thermally sensitive resins are processed at temperatures recommended by the material supplier with minimal resin shear, thus maintaining the resin properties. The Accu-Valve EX line is also available in a liner valve style which allows the Mold-Masters® supplied transfer seal to act as
a replaceable gate insert in the mold with only a small witness mark. Ideal for technical parts and filled resins.

flexibility
Precise flow channels in the liner have eliminated fins that cause dead spots
Continuously guided pin
Pin is guided in two key areas:
1. above the EX liner 2. directly in the gate area
Ease of integration is achieved by two tolerance requirements:
1. at the gate seal 2. the gate diameter itself
