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.

Who this is for

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.

What we deliver

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.

Operational realities

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.

Designed for African conditions

What we design for that most imports don't consider.

African realityWhat it means for design
Resin price and grade volatilityLines spec'd to run mixed regrind ratios cleanly, with auto-blending
Power quality issues kill servo systemsStabilised power supply, line conditioning, robust servo drives
Tooling lead times can stall a launchTool design and validation project-managed in parallel with line build
Operators turn over frequentlyHMI in plain English, recipe-based operation, process-critical parameters locked
Scrap is the silent killerEvery CISH line ships with scrap, cycle-time, and OEE on a dashboard from day one
Indicative project economics
