Thermonic : Arburg temperature controller

Thermonic SN 46.531

Arburg injection moulding machine allrounder K, H and H-D have dedicated PID temperature controllers
for cylinder heating, nozzle heating  at the plasticizing unit.

These temperature controllers  i.e. Thermonics have a D-PID characteristics therefore, no temperature peak on start-up and no steady deviation. It has 3+1 configuration of Thermonics, i.e. 3 Thermonics for cylinder heating zones and one Thermonic for nozzle heating; ensures precise temperature profile on cylinder and nozzle.










Thermonic has an in- built under temperature protection circuit so that screw rotation is inhibited if
cylinder temperature is too low.

It consists of following main sections:
A. Input signal sampling and amplification.
B. PID regulation circuit.
C. Overload protection circuit &  SSR protection circuit.
D. Under temperature protection circuit.

There are many models of temperature controllers which were used on Arburg machines.

Thermonic SN 36.346, SN 31.980,SN 34.600, SN 39.507, SN 31.980 :  switching the supply to heater band via triac.

Thermonic  SN 40.787, SN 40.788, SN 46.530, SN 46.531, SN 52.022 :  switching the supply to heater band via SSR.

 Thermonic  SN 53.013, SN 71.356, SN 71.357  :  switching the supply to heater band via SSR.

Sanjadha Enterprises expertise in  repair and calibration of Thermonics of all models.
We have adequate stocks of spare parts and components required for repair of Thermonics.
We undertake complete overhaul, repair and reconditioning of Thermonics.

Hot Runner temperature controller Hi-Q ( supplied by Synventive/Dynisco)

Synventive 8 zone Hi-Q hot runner temperature controller



It is a 2 zone temperature controller with versatile operation required for hot runner temperature controller. It was available  in single zone ( HIQBOX1S), 4 zones (HIQBOX4) ,8 zones ( HIQBOX8) , 12 zones (HIQBOX12)  and 24 zones (HIQBOX24) cabinets.

Synventive 2 zone Hi-Q hot runner temperature controller-side view


Synventive 2 zone Hi-Q hot runner temperature controller
Since March 2010,  we repaired more than 70 such  cards. Typical problems faced by Hi-Q temperature  controller cards are :

1. ON-OFF problem: It switches off during operation and switches on after some time.
2. Actual Temperature indications :   0 ° C  /   0 ° C
3. Actual Temperature indications : 500 ° C  /   0 ° C, 0 ° C  /   500 ° C
4. Actual Temperature indications : tc ¯ ° C  /    tc ¯ ° C ,  tc ¯ ° C  /    0 ¯ ° C
5. Actual Temperature indications : 0 ° C  /   SHO  ° C,  SHO  ° C  /   0 ° C, SHO  ° C  /  SHO ° C                                                 
6. No display
7. No display -complete dead unit.

Various reasons for failure of Hi-Q cards are as given below:
a. Unhealthy 3 phase + neutral+ earth connections.
b. Improper connections to thermocouples and  heaters.
c. Malfunctioning of cooling fans installed on the cabinet.
d. Incoming mains voltage with severe power surges.
e. Components failure due to ageing,dust,moisture etc.

Now we are confident that in 99.0% cases we can revive  Hi-Q card completely irrespective of the the nature of problems. 1.0 % cases is when the card is subjected to severe power surges ( short duration voltage current spikes in the electrical environment)  for longer period/periods. We have upgraded our testing + repair facilities and also the required stock of spares needed to achieve this.

To avoid problems due to power surges, it is possible to retrofit power conditioning unit internal or external to each cabinet box along with surge protection devices. This will provide the utmost maximum safety to the Hi-Q temperature controller cards and heaters.
