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 |

Every plastics and packaging line on one ladder
Every line we deliver in this industry, with its entry, mid and industrial tiers in 2026 USD and the first question that decides the tier. The full scenario map, with site conditions and the guide that prices each situation, is at production lines by scenario.
| Line | Entry tier | Mid tier | Industrial tier | The first question we ask |
|---|---|---|---|---|
| Injection moulding | 150–300 t · US$30–75k (servo +10–15%) | 400–500 t · from US$100k | Multi-machine shop, per project | Which part, and who pays for the mould? |
| PET preforms and bottles | Injection machine + preform mould + blow moulder | Per bottle and cavity count | Per project | What bottle, what volume? |
| Bag making | Basic · US$8k | Servo · US$40k+ | Multi-line converting, per project | What film, what print? |
| Pipe and profile extrusion | Single-screw · from US$20k | Multi-layer · US$200k+ | Per project | Which product standard will the pipe be tested against? |
| Recycling | Wash line 300–1,000 kg/h · US$120–350k | Pelletising added, per project | Per project | Do you have bale supply contracts? |
| Paper converting and egg trays | Toilet paper converting · US$10–50k; egg tray forming · from US$8k | Small egg-tray plant · ~US$30k; automatic converting to the US$1M class | Paper mill: a different investment | Converting jumbo rolls, or making paper? |
Bands are indicative equipment capex in USD unless stated as landed and commissioned; they are the same bands our price guides publish. Machinery is priced in US dollars and the rand cost moves with the exchange rate.
Common questions.
On the quote, buying direct is usually cheaper; for the project as a whole, not necessarily. The quote assumes you already have six capabilities — specification, supplier screening, negotiation, shipping and duties, commissioning, maintenance — and can carry the risk of the project failing. What those cost you, in time and in tuition, is the real comparison: Is buying through CISH more expensive?
More packaging and recycling lines, priced.
PP woven bag machine prices
Maize-meal, feed and cement sacks from tape line to cut-sew.
Paper bag, cup and box machine prices
Paper bags, cups, carton converting and exercise books.
Tyre recycling plant cost
Crumb rubber lines and the licences behind them.
