DORST Product Lines We Repair
Our engineers are trained on the full DORST product range. Below are the major product families we service.
DORST HM Series Hydraulic Press Control Units
Programmable hydraulic press controllers managing pressure profiles, stroke cycles, and force feedback in tablet pressing and metal forming applications. Common issues include pressure transducer signal loss, solenoid valve control failures, and PLC communication breakdowns during high-volume production runs.
DORST Tablet Press Automation Electronics
Integrated electrical cabinets and motor control systems for automatic tablet press operation, including feeder synchronization, turret indexing, and ejection control. Faults commonly involve motor encoder feedback issues, relay logic failures, and sensor interface degradation in humid pharma environments.
DORST P Series Industrial PLC Modules
Embedded programmable controllers for press process monitoring, recipe management, and batch cycle automation. Typical faults include firmware corruption, memory card failures, Ethernet port degradation, and interrupt timing issues under high-speed production cycles.
DORST Pressure and Temperature Sensor Interface Units
Signal conditioning modules converting hydraulic pressure, temperature, and displacement transducers into digital process signals. Common failures include amplifier offset drift, analog-to-digital converter degradation, and shielding issues causing noise in EMI-heavy shop floors.
DORST Force Feedback Control Systems
Closed-loop force regulation electronics for precision pressing applications in pharmaceuticals and advanced materials. Typical issues involve load cell calibration drift, feedback amplifier noise, control oscillation, and proportional valve response lag.
DORST Emergency Stop and Safety Relay Modules
Safety-certified electrical modules managing press start/stop interlocks, emergency shutdown, and guard door sensing. Failures typically include relay chatter, contact corrosion in high-humidity pharmaceutical environments, and 24V power supply degradation.

Common DORST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DORST equipment arriving at our workshop.
- ✓Hydraulic pressure signal loss or instability — DORST pressure transducers degrade from contaminated hydraulic fluid, moisture ingress, or mechanical shock during press operation. Signal cable shielding degradation in EMI-heavy environments causes intermittent reading loss.
- ✓PLC program memory corruption or unexpected system reset — DORST P-series controllers suffer memory faults from power supply voltage spikes, loose backup battery connections, or firmware update interruptions. High humidity in pharmaceutical plants accelerates PCB trace corrosion.
- ✓Motor encoder feedback missing or erratic counts — DORST tablet press feeder and turret drive encoders fail due to connector corrosion, cable abrasion near moving parts, or internal optical sensor contamination. Vibration-induced loose connections cause intermittent signal dropout.
- ✓Solenoid valve not energizing or holding pressure — DORST hydraulic solenoid coils open-circuit from moisture, mechanical stress, or driver transistor failure in control electronics. Valve spool stiction occurs from fluid contamination or manufacturing debris left in passages.
- ✓Force feedback control oscillation or erratic pressure cycling — DORST closed-loop pressure controllers oscillate when proportional valve response becomes sluggish from internal wear or when load cell amplifier gain drifts. Poor tuning after component replacement also causes hunting behavior.
- ✓24V auxiliary power supply ripple, dropout, or shutdown — DORST press control cabinets use standard industrial 24V supplies that fail from blown filter capacitors, shorted load circuits, or transformer fusing. Thermal stress in poorly ventilated cabinets shortens component life.

Frequently Asked Questions — DORST Repairs
Do you repair DORST equipment anywhere in India?+
Yes. Synchronics repairs the complete DORST product range including hydraulic press controllers, automation electronics, sensor interface modules, and safety systems across all Indian states. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and 100+ cities. All repairs are handled at our main facility in Vadodara, Gujarat, where we maintain DORST spare parts, calibration equipment, and test rigs for pharmaceutical and industrial press systems.
What is the typical turnaround time for DORST tablet press control system repair?+
DORST tablet press control units typically require 7-10 working days for complete diagnosis, component replacement, calibration, and production-line testing. Critical systems in high-volume pharmaceutical plants can be expedited to 3-5 days if components are in stock. We provide real-time status updates and emergency same-facility repairs for urgent breakdowns. Synchronics maintains a stock of common DORST solenoid coils, pressure transducers, relay modules, and 24V power supplies to minimize downtime.
Can Synchronics recalibrate DORST force feedback and pressure control systems to exact specifications?+
Yes, we perform full recalibration and tuning of DORST closed-loop force and pressure control systems against DORST OEM specification sheets. Using precision test equipment, we verify load cell linearity, proportional valve response time, PLC cycle timing, and pressure regulation accuracy within pharmaceutical GMP tolerances. Our engineers document all calibration data and provide you with certificates for compliance audits and regulatory filings.
Does DORST equipment fail often, and what preventive maintenance should our plant do?+
DORST hydraulic press systems are highly reliable when properly maintained. Most failures we see in Indian pharmaceutical plants stem from contaminated hydraulic fluid, moisture in control cabinets, poor electrical grounding, and overdue sensor maintenance. We recommend quarterly hydraulic fluid analysis, annual cabinet inspection and cleaning, biannual pressure transducer recalibration, and monthly solenoid valve functional testing. Synchronics offers annual preventive maintenance contracts covering all DORST equipment on your production floor.
What is your experience with DORST systems in Indian pharmaceutical manufacturing?+
Synchronics has repaired DORST tablet press automation, filling-machine hydraulics, and powder compression systems in 50+ Indian pharmaceutical facilities including both branded and CDMO plants. We understand GMP documentation, batch traceability logging, and electrical safety standards required in pharma manufacturing. Our engineers are familiar with common fault patterns in DORST equipment used in 24/7 high-volume Indian pharma operations and can advise on upgrade paths and reliability improvements.
How do I send my DORST unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DORST drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DORST repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DORST unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
