Product Overview

The KR‑1008EM portable multi‑channel tie‑bar clamping‑force tester is a field‑oriented measuring system built for injection‑molding and die‑casting machinery. Equipped with four magnetic‑mount strain‑sensing probes and a handheld digital read‑out terminal, it captures micro‑strain deformation on four tie‑bars simultaneously after mold‑locking. Readouts can be displayed in micro‑strain (με), kN or ton‑force units.

Technicians adjust individual tie‑bar tension according to real‑time multi‑channel readings to achieve uniform force distribution across all four columns. This mitigates premature tie‑bar fatigue‑fracture risk, minimises mold offset caused by uneven loading, and reduces molding defects such as flash and dimensional deviation on finished plastic parts. Thanks to strong‑magnet adsorption installation, no mechanical modification or bonding work is required on tie‑bars, enabling quick setup, field calibration and periodic machine‑health auditing for injection‑ and die‑casting workshops.

Core Product Competitive Advantages

1. Four‑Channel Synchronous Acquisition with Hand‑Held Touch‑Screen Terminal Independent 4‑channel data acquisition module reads strain data from all four tie‑bars at once. Colour touch‑screen handheld unit displays per‑channel values, average and total force. Operators switch measuring‑unit (με / kN / ton‑force) directly on‑device for on‑site comparative adjustment.
2. High‑Strength Magnetic‑Adsorption Sensor Mounting Each sensor assembly uses dual‑magnet configuration with 2×380 N magnetic holding‑force. Sensors firmly cling onto tie‑bar outer surface without glue, drilling or fixture clamping. Fast attachment and detachment greatly cut setup time during machine‑commissioning or routine inspection cycles.
3. Lab‑Grade Measuring Precision for Industrial‑Site Conditions Built‑on bonded strain‑gauge principle (350 Ω strain‑foil, half‑bridge compensation circuit). System accuracy reaches 2 %FS, repeatability within 1 %FS and hysteresis ≤0.5 %FS. Reliable performance for dynamic mold‑closing impact‑load on real production machinery.
4. Portable Complete‑Set Hard‑Carry‑Case Design The whole measuring kit including display unit, four sensors, signal cables and accessories is housed inside shock‑proof hard‑shell transport case. Compact form allows easy movement among multiple injection‑molding presses within plant floor.
5. Expandable Digital‑Output Interfaces Optional USB data‑export enables recording measurement logs to PC for trace‑quality‑archive. Optional analog 0‑10 VDC output supports connection to external monitoring system. Suited for machine‑acceptance testing, maintenance troubleshooting and long‑term process‑trend logging.
