Thermoplastics Injection Molding Specialist

Can You Stabilize a Process and Restore Standard Fast?

If you can walk up to a Tayu vertical injection-molding cell, home a Kawasaki 6-axis robot, steady a TCU, and have parts flowing within minutes—while keeping documentation airtight—you’re who we’re looking for. You’ll produce insulator pins for handheld conducted energy devices using a tightly integrated workcell: robots, vibratory bowl feeders and runs, camera vision, a table cutter, and washer capping stations. The challenge: deliver on time, tune automation with intent, and keep the process inside control limits.

Your Challenges

• Pre-start safety checks: guards/interlocks, e-stops, light curtains, hot-oil lines, rotary table, and any spill/leak conditions.
• Start-up sequence: home the Kawasaki 6-axis robot; stabilize the TCU at 320°F / 160°C for 20 minutes; bring barrel heats to 698°F / 370°C for 20 minutes; turn on the manifold for hot tip controllers at 395° / 202° C.
• Apply LOTO and complete documented shutdown for press, robot, capper, and TCU.

• Stage molds (MPJ 1097, MPJ 1238), EOAT, shells, pins, resin; microscopes and caliper ready; confirm Matsui dryer settings and parameters.
• Install molds; confirm clamp plate alignment and platen cleanliness; torque clamps to specification and record values.
• Connect TCU supply/return, leak-check, and verify temperature stability.
• CTQ pulls at start or shift change: MPJ 1097—16 parts total (1 per cavity per side). MPJ 1238—32 parts total (2 per cavity per side). Deliver to the Quality Technician.

• Control temperature/pressure/velocity; watch cushion, fill time, transfer position, pack pressure, and cycle time.
• Maintain UCL/LCL; document any drift and execute reaction plans.

• Robot: home, validate safe zones, update points after mold changes.
• Bowl feeders: tune vibration amplitude; ensure orientation rules—Work Cell 1 (MPJ 1097): MMM0161 shell MMM0162 pin; Work Cell 2 (MPJ 1238): MMS0402 shell MMM0162 pin; Capping Stations 1 & 2 (S01908): MPJ 1238 body MMS0403 washer.
• Vision system: own the dataset lifecycle—image capture, model training, periodic re-validation on Work Cells 1 and 2.
• Table cutter: replace pads/cutters; set height via HMI with ±0.020 millimeters tolerance (MPJ1097 nominal 5.69; MPJ 1238 nominal 4.35 millimeters).
• Capping station: calibrate height sensors; confirm cap presence and orientation.

• Travelers must be complete and current: PD-WI001-F01 (MPJ 1097), PD-WI001-F02 (MPJ 1238), PD-WI001-F03 (S01908). Initial/date each operation.
• Every 30 minutes: caliper-based height checks; hold on any out-of-spec. Tolerances—MPJ 1097 ±0.020 mm; MPJ 1238 ±0.010 mm.
• Microscope visual inspections per acceptance criteria; log on the appropriate documents (Traveler, Visual Inspection Sheet, Height Check Sheet).

• Daily verifications: lube levels, leaks, heater band status, TCU temperature/flow, dryer dew point.
• Alarm response: clear jams, reseat connectors, replace common wear parts, then document.
• Root-cause and recover vertical press and capping-station automated controls; escalate within defined time and capture fault/cause/action/verification.

• Follow drying specifications (temperature/hours, dew-point targets) with sealed conveyance to the hopper for Radel material.
• Record material lot numbers on the Traveler and in NetSuite.
• NetSuite: enter the number of MPJ 1238 parts made; link to lot numbers for bodies, pins, resin (operations confirm, assembly build, scrap).

What It Takes

• Hands-on experience with vertical injection molding presses and integrated automation.
• Setups/changeovers, first-article inspections, and in-process control to defined limits.
• Basic robot ops (home, jog, point verification) and EOAT handling.
• Comfort with calipers and microscope; accurate records.
• LOTO proficiency and an unwavering safety ethic.
• Read/interpret blueprints, drawings, and work instructions.
• Mechanical aptitude; systematic root-cause approach.
• Clear communicator; thrives independently and on a team in a fast-paced, shift-based environment.
• HMI navigation/adjustments; NetSuite production entry; Microsoft Office for reporting.
