Plastics and packaging — where speed, scrap, and shift consistency decide profitability.
A small reduction in scrap or a modest cycle-time improvement falls straight to the bottom line in plastics and packaging. CISH supports lines designed and instrumented to make those losses visible, improve shift consistency, and give plant teams practical control over the variables that matter most.
For plastics and packaging manufacturers where process discipline drives margin.
Moulding operations scaling output
Factories adding machines, cells, or auxiliaries while trying to protect cycle time, tooling uptime, and operator consistency.
Packaging producers managing scrap risk
Businesses where resin cost, changeovers, and reject rates quickly decide whether the plant is profitable.
Plants integrating processing and conversion
Projects linking extrusion, printing, lamination, pouching, recycling, or downstream handling in one production flow.
Teams that need better visibility
Operations where production data, cycle-time drift, or scrap behaviour still lives in manual reporting rather than on a usable dashboard.
Sub-categories we cover.
Injection moulding
80–3 000 tonne machines and multi-machine cells. Hot runner, robot take-out, in-mould labelling. Auxiliaries: dryers, dosers, chillers, granulators. Mould tooling.
Blow moulding
PET stretch-blow (single-stage and two-stage, 1-tonne to high-speed rotary). HDPE/PP extrusion blow moulding — jerry cans, bottles, drums. Industrial blow moulding 25–220 L.
PET preform & caps
32-, 48-, 72-, 96-cavity preform systems. Closure systems (CSD, flat cap, sports cap).
Extrusion
Pipe (HDPE, PP-R, PVC). Profile (windows, doors, decking, cable trunking). Sheet (PP, HIPS, PET for thermoforming). Film (blown LDPE/HDPE, cast PP).
Flexible packaging
Multi-layer co-extruded film. Lamination (solvent and solventless). Slitting, rewinding. Pouch making — stand-up, sachets, spouted.
Printing & recycling
Flexo, rotogravure, digital printing. Roll-to-roll converting, die-cutting. PET washing lines (bottle-to-flake). HDPE/PP washing and pelletising.
The issues that usually matter more than nameplate speed.
Resin and tooling variability
Material cost, regrind strategy, and tooling readiness can wipe out the gains from buying a faster machine if the process is not controlled properly.
Shift-to-shift consistency
Many plastics plants lose more money through unstable operation and hidden scrap than through obvious major breakdowns.
Data that never reaches action
Dashboards only matter when operators, supervisors, and maintenance teams can use them to change behaviour on the floor.

What we design for that most imports don't consider.
| African reality | What it means for design |
|---|---|
| Resin price and grade volatility | Lines spec'd to run mixed regrind ratios cleanly, with auto-blending |
| Power quality issues kill servo systems | Stabilised power supply, line conditioning, robust servo drives |
| Tooling lead times can stall a launch | Tool design and validation project-managed in parallel with line build |
| Operators turn over frequently | HMI in plain English, recipe-based operation, process-critical parameters locked |
| Scrap is the silent killer | Every CISH line ships with scrap, cycle-time, and OEE on a dashboard from day one |
