Multi-circuit systems: the flow decides the part
In a multi-cavity mold, the most unfavorable cavity marks the cycle and rejection of the entire part. The real cause is not the temperature: it is the flow. Measuring and balancing the flow rate of each circuit equalizes the cavities.
The temperature is the symptom; he flow is the cause. A multi-circuit system measures flow and temperature per circuit—and, optionally, return pressure—and balances them independently, up to 12 circuits, so that all cavities work the same: homogeneous piece, faster cycle and traceable process.
The most unfavorable cavity marks the cycle
In a mold with several cavities, it is enough for one to deviate to condition all of them. The hottest—or coldest—cavity sets the cycle time and reject rate for the entire part.
There is nothing to gain from three cavities being fine if the fourth forces you to lengthen the cycle or throw away pieces. The set is only as good as its worst circuit.
shared collector, unequal distribution
The cavities are parallel circuits. Each one has a different length and geometry, and therefore a hydraulic resistance different. Fed from the same collector, the flow is distributed unevenly.
If the flow rate is not equal, the heat extraction is not equal, and the temperature disperses from one cavity to another. The passive collector distributes according to the resistance of each circuit, not according to what each zone needs.
The flow is the lever
Temperature is the result; he flow is the lever that extracts heat from each cavity. That is why the flow is measured and balanced, circuit by circuit.
Measure and balance each circuit
A multi-circuit system gives a complete hydraulic view of the mold: read caudal to balance each circuit to its actual demand, temperature round trip—whose ΔT reveals the load—and, optionally, return pressure as an early warning of obstruction or loss.
By regulating each circuit to its target flow rate, the temperature equalizes itself: identical parts from the first to the last and a faster and more stable cycle.
Two families, as you need visual reading or electronic management
Marse manufactures two families of equipment to distribute and control the flow per circuit. Both are modular (2 to 12 zones) and share the same idea: give each cavity the flow it needs.
Flow regulators
Caudalímetros con rotámetro y termómetro por circuito y grifos de regulación manual. Lectura inmediata del caudal de cada zona, sin electrónica; el modelo EWFR añade pantalla de 7" y alarmas. Compatibles con circuitos abiertos y cerrados.

A hydraulic vision of all the mold
Sistema modular que regula hasta 12 circuitos desde un único equipo, con medición de caudal y temperatura por circuito (presión de retorno opcional), pantalla táctil de 7", gestión de datos e interfaces Industria 4.0. Para una lectura visual sencilla, los caudalímetros (WFR / EWFR / RWFR) ofrecen rotámetro y termómetro por circuito, hasta 160 °C en circuitos cerrados.
Common questions
Why measure flow and not just temperature?
Because temperature is the result and flow is the cause. The flow drags the heat from each cavity; When something fails, it drops before the temperature. By balancing the flow per circuit, the temperature equalizes itself.
Why isn't a passive collector enough?
Because it distributes the flow according to the hydraulic resistance of each circuit, not according to what each area needs; the result is uneven temperature. Circuit control adjusts each one to its demand.
Manual or proportional regulation?
Manual regulation (ball valves or taps) is robust and economical. Automatic proportional (Flow PV model) modulates each channel electronically for the finest control. Both are integrated into the same system.
How many circuits and at what temperature?
Up to 12 circuits per team. The electronic distribution reaches 180 °C (Flow 180, also with thermal oil); flowmeters, up to 160 °C (RWFR 160) in closed circuits.
Can it be used with glycol water or oil?
Yes. Water models accept water and water + glycol; The Flow 180 also accepts thermal oil up to 180 °C.
