Machine Controls and Sensors
At Hunkar our focus is to detect and eliminate potential process problems before bad parts can be produced. Hunkar designs and builds a wide variety of blow molding controls, injection controls, sensors and transducers, valves, as well as preemptive data acquisition systems and equipment that can enhance virtually every plastics molding process.
Sensors and Transducers
Hunkar Gold Standard™ Sensors and Transducers: Where Precision and Increased Profits Begin
Often, plastics molders use sensors and transducers whose accuracy and reliability differ greatly unit to unit. This is usually due to wide tolerance variability. To the molder, this requires re-calibrating the machine to a new sensor whenever one is replaced. Additionally, it can mean that a sensor may not be precise enough to assure acceptable tight control limits required for all jobs. Hunkar Gold-Standard instrument grade, National Institute of Standards and Technology (NIST) traceable sensors and transducers are the best solution.
Hunkar Gold-Standard Sensors are at least 10-times more accurate than typical industrial grade sensors. Gold-Standard sensors eliminate the need to recalibrate your machine during future sensor replacement, because each sensor is electrically identical. You'll also enjoy significantly longer sensor life, due to Hunkar's durable construction. Other Gold-Standard benefits include:
- Because each sensor is electrically identical, the need for recalibration of control systems if a sensor is replaced is virtually eliminated
- Delivers precise, impartial data for use as NIST traceable criteria for quality acceptance programs
- Enables faster reuse and transfer of successful setups for saved jobs
- Affords rapid and more precise diagnostic capabilities for machine repairs and process improvements
- Renders accurate engineering data developments to process specifications
- Manufactured to MIL specs to assure minimal fatigue throughout sensor life
- Fully certified for quality, span, offset and linearity against NIST certified standards
Hunkar Gold-Standard Accuracy provides required third party, independent, traceable data for quality program support such as: QS 9001, ISO 9000 and ISO 14000. Every Hunkar Gold-Standard sensor and transducer is lab tested according to strict procedures to ensure absolute uniformity; traceable to NIST standards.
