Alignment of Parisons During Small Bottle Manufacture

Ionized air applied between parisons to reduce deflection
Problem

Closely spaced small extrusion heads often cause parison deflection and lower yield as the mold pinches the parisons. Tight spaces around the heads and the top of the mold also make it hard to deliver ionization effectively, as proximity to earth reduces ion reach.

Solution

Install Meech 261 Flexi Nozzles to blow ionized air between parisons. This minimizes deflection without cooling the parison. The compact nozzle can be positioned above the mold to direct airflow along the parison length, reducing contact with the mold tool—enabling reliable small double-cavity production where bars or air curtains can’t reach.


CD & DVD Delamination During Manufacture

DVD bonding process illustration
Problem

DVDs are formed by bonding two CDs. Like-polarity surface charges can repel during bonding, creating pinholes and weak adhesion.

Solution

Charge one disk with opposite polarity using a Meech 993R Generator Bar to achieve consistent, defect-free bonding.


Cleaning uPVC Profile Extrusion After Machining or Pre-Decoration

Cleaning swarf from rigid plastics extrusion
Problem
  • Warm, highly charged profiles collect swarf after sawing.
  • Operators receive painful shocks; swarf spreads and contaminates equipment.
  • Painting/foil wrap is hindered by swarf adhesion.
Solution

Place Meech 957 Ionizing Air Curtains to strip and neutralize swarf while neutralizing the profile. Add a barrier at the saw box extraction to improve capture and prevent wider contamination.

Contamination Control for Door Seal Manufacturing

Ionizing air curtain for rubber extrusion
Problem

Extruded rubber (e.g., automotive door seals) attracts contaminants, risking batch rejection and penalty claims.

Solution

Use a Meech 957 Ionizing Air Curtain to assist cooling and neutralize charge, reducing contamination risk.

Contamination Control in Thermoforming

JetStream ionizing air knife system
Problem

Sheets must be free of dust/swarf before forming; charges created during forming re-attract contamination and can shock operators.

Solution

For large sheets use the Meech JetStream Ionizing Air Knife; for smaller sheets use a 957 air curtain or 954 ionizing gun. Neutralize charges generated during forming to prevent re-contamination and shocks.

Contamination Control on Injection Moulded Products

IML contamination control at conveyor discharge
Problem

As parts cool, electrostatic charge attracts contaminants from conveyors and ambient air—especially on IML jobs.

Solution

Mount a Meech 971IPS Bar at the end of the conveyor near the set-down area so every part passes through the ion field; continuous ion flow suppresses re-charging while cooling.

Conveying Plastic Granules Activating Metal Detector

Inline flow tube before metal detector
Problem

Electrostatic discharges in ducting trigger metal detectors, causing false rejects and waste.

Solution

Fit a Meech 913 Flow Tube inline just before the detector to neutralize charge and prevent false alarms.

Conveyor Problems with Plastic Blow-Moulded Bottles

Hyperion bars mounted over conveyor
Problem

Conveyed bottles accumulate high static—pulling dust, increasing pre-fill cleaning, and shocking operators.

Solution

Install Meech 971 or 929IPS Hyperion Bars above the conveyor to bathe bottles, belt, and nearby operators’ hands in balanced ions, neutralizing charge continuously.

IML Decoration of Plastic Moulds Using Static Pinning

Label pinning for IML
Problem

Accurately locating and holding labels inside the mould is difficult; any shift leads to rejects.

Solution

Use a static bar or charging head to pin the label to the mould (robot or manual). After placement, the mould closes and encapsulates the label for consistent positioning.


Mouldings Sticking to Tool Face During Injection Moulding

Ionizing air curtain aiding part release
Problem

Small/light parts cling to the tool due to static, risking tool damage and slowing cycle times.

Solution

Position a Meech 959IPS above or beside the tool to discharge the part for reliable release. Pulse air only when the tool is open to save air and avoid cooling the tool.

Neutralising Static Generated While 3D Printing

929IPS bar used between print passes
Problem

Static on model powder mixes with support material, degrading finish and strength; UV curing generates charge that repels powder during passes.

Solution

Neutralize the build area between passes with a Meech 929IPS bar to control charge and stabilize deposition.

Operator Shocks During Electrical Cable Manufacturing

Problem

Plastic coating processes leave high charge on conductors, causing painful shocks during handling.

Solution

Discharge the coated wire during rewind with a Meech 929IPS bar to control build-up.

Operator Shocks in Tyre Manufacture

971 system neutralizing extruded rubber on carrier
Problem

Rubber extruded onto a carrier belt charges heavily as it separates, creating shock hazards.

Solution

Use a Meech 971 or 935 system (position-dependent) for effective long-range neutralization.

Print Quality Problems with Inkjet Printing on uPVC Extrusion

Ionizing bar before inkjet head on uPVC profile
Problem
  1. Dust is attracted to the print area.
  2. Ink jets deflect; edges feather.
  3. Electronics can suffer ESD faults.
  4. Deflector plate contamination causes downtime.
Solution

Place a strong Model 915 Ionizing Bar before the head to neutralize charge and stabilize print. A Model 940BE nozzle is a viable alternative.

Static Problems Causing Blow-Moulding Parison Misalignment

Long-range ionization over parison and mould entrance
Problem
  1. Multiple parisons share the same charge and repel, missing the mould and creating stress lines.
  2. A single parison can be attracted to metalwork and misplace.
Solution

Meech 971 / 971IPS deliver long-range ionization from the extrusion head to the mould top without air, ideal for thin parisons that can be disturbed by airflow. Where space is tight, use a 929IPS bar.

Swarf & Contamination Control on Extruded Plastics

Air curtain cooling and neutralizing tube extrusion
Problem

Static builds as tubes cool and during drying/machining, causing swarf and dust pick-up and later abrasion or finishing defects.

Solution

Neutralize charge to prevent attraction. A Meech 957 Air Curtain both cools and neutralizes, reducing swarf adhesion.

Controlling Static Charges in Air Conveyor Diverter Valves

Bulkhead nozzles fitted to diverter valve tubing
Problem

Waste film or granules become charged and cling to the gate, jamming or blocking the diverter valve.

Solution

Fit Meech 261 Bulkhead Nozzles to the tube to neutralize charge and keep product flowing.


Static Control During Film Rewinding

Ionized air blower covering full reel width
Problem
  1. Operators receive painful shocks.
  2. High embedded reel charge causes downstream issues.
  3. Dust attracts from long distances, contaminating film.
Solution

Use a Model 935 fan-driven ionized air blower for long-range, gentle, wide-area ion delivery that neutralizes the entire roll. Optional fan filters ensure clean air to the reel.


Static Pinning Film on a Cast Film Extrusion Chill Roller – 995 CLAW

995-CLAW pinning heads holding edges on chill roller
Problem

Cast film necks as it cools on the chill roller, narrowing width and reducing quality. Compressed air edge control is noisy, costly, and can mark film.

Solution

Use Meech 995-CLAW pinning heads on each side to hold edges electrostatically. Each head offers lateral/rotational adjustment with three resistively coupled titanium pins for strong, safe pinning. Pair with a 30 kV 992v3 negative generator (remote on/off) for simple operation.

Setup tips: use the minimum charge required; keep pins 10–15 mm from the film for a gentle, broad charge; neutralize before rewinding to prevent telescoping and edge defects.
