Venango’s heated platens with even temperature control allow manufacturers to introduce zone-specific temperatures while applying forming pressure to molds or directly to materials. This heat uniformity is crucial, as it affects the dimensional stability and hardness of the component being produced and controls for minimal quench distortion and cracking.
Venango’s MultiZone Heated Platens use electricity to achieve consistent mold temperatures and have unmatched reliability. With dedicated zone control, tracking and sustaining temperatures is quick, accurate, and reliable.
How does a Venango MultiZone Heated Platen provide even temperature control? Here are two common questions, answered:
Each platen’s unique ability to control the temperature of different regions, or “zones,” means that individual mold areas only receive the heat necessary for the treatment of the material contained there. This acute mold-temperature control is a hallmark of Venango’s MultiZone Heated Platen.
In compression molding, as the value of the material and part rises, so does the importance of controlling the uniformity of heat transfer to the mold cavity. Single zone heating platens can not correct temperature variation across the mold face, negatively impacting manufacturing and part quality and increasing scrap rates.
“Maintaining good temperature uniformity over the surface of a platen is extremely difficult. The MultiZone platen is superior to heat tube platen technology because the key is uniform mold temperature, not uniform platen temperature. MultiZone platens with even temperature control give molders six sigma capabilities,” said Nyla Vogel, Sales Manager, Venango Machine.
Venango’s MultiZone heating platens and their comprehensive control systems reduce mold surface temperature variation by almost 400%, delivering the precise control necessary to ensure a good product and faster recoveries, saving time and money.
Platens with even temperature control provide quick, consistent production with minimal waste and downtime – the ultimate goal in manufacturing. A heated platen press should last for many production cycles without warping or diminishing its ability to provide consistent temperature. Selecting a platen with the best heat uniformity is critical to ensuring the longevity and performance of a manufacturer’s platen equipment.
Many industries benefit from Venango’s platens with even temperature control, including:
When paired with technologically advanced control panels that closely monitor heat distribution, manufacturers can rest assured that their molds won’t suffer from common pitfalls that cause production breakdown.
In comparing single-zone versus MultiZone heating platens, temperature uniformity improved from 25 degrees off-target to only 0.4 degrees. Further, the CPK increased from -1.47 to 2.94 while lowering the standard deviation from 3.2 to 1.08. During molding, the process window dropped from +/- 9.6 to +/- 3.2, ultimately leading to shorter cure times and lower scrap rates.
Maintaining exceptional temperature uniformity over the surface of a platen and on a mold itself is crucial. At Venango, our exclusive MultiZone Platen technology makes heat control easy and precise, and our control panels are equipped with sophisticated software to allow careful temperature monitoring. When the quality of your product depends on even heat, Venango’s MultiZone Platen is the best choice.
