Recently, Heidelberg released news detailing the precautions that must be taken during the lockdown period for Heidelberg postpress equipment.

General Maintenance

Check input voltage levels with the support of electrical professionals before powering ON the machine
Safeguard the machine from dust, rats/rodents with protective covering
Park hand pellet trucks in correct positions
Clean area surrounding the equipment
Clean beneath the machine by blowing pressured air
Clean gripper bar chain and run the press for 20 – 30 minutes
From lubrication menu (HMI Display) activate manual chain lubrication for 10 – 15 minutes (the delivery chain should be lubricated unit chain looks wet with oil)
Install traditional/glue mouse traps at the production room
Remove all flammable, fume-genrating solvents in surrounding equipment and store with caution
Dispose all waste produced by machine.

Feeder Station

Apply light coat of oil on suction head forwarding sucker bar, lifting sucker bar and blower heads
Apply thin coat of grease or oil for all sliding parts on suction head, side stops and pile centering threaded shaft
Apply thin coat of grease on feeder pile chains.

Feed table and Infeed station

Lubricate centralized runner adjustment parts with recommended lubricant
Clean and lubricate tape tabletop frame, hold down runner shaft, tape rollers
It is highly recommended to reduce tape tension if the lockdown is more than 8 days
Clean and lubricate infeed area, side lay, front lay, sliding parts and sliding accessories should be lubricated with light coat of oil (make sure all sensors are dust free and oil free)
Release tension from side-lay pulling roller

Die-cutting station

Clean the plastic top surface of the upper chase with acetone and park the chase inside machine or in position shown above
Thoroughly lubricate 1mm plate, 4mm plate or 3mm plate with oil and park inside machine
Lubricate chase parking guide rollers and exposed parts with thin coat of oil
Clean oil cooler heat exchanger

Die-cutters with stripping station

Apply thin grease coating on stripping movable frames, and chrome-coated fixed shafts
Clean reflectors in platen outlet and stipping outlet with slightly wet cloth and dry immediately. Ensure that the cleaning cloth is made of soft and anti-scratch material
Clean breather filters in the platen outlet
If machine oil needs to be replaced, do it at the time when print production is restored (when the machine kicks back into production)

Foiling station

Clean honeycomb chase with acetone and apply thin coat of oil on both surfaces
Clean telescopic foil loading shafts and lubricate sliding parts
Clean reflectors in platen outlet and foil-loading station outlet with slightly wet cloth (made of soft, anti-scratch material) and dry immediately
If machine oil needs to be replaced, do it at the time when print production is restored (or when the machine kicks back into production)
Clean special-coated shafts with acetone and lubricate with thin coat of oil, or chain lubricant spray
Clean the surface of all rubber rollers with acetone and keep away from drive shafts. It is important to ensure that rubber rollers are not in contact with drive shafts (social distancing policy is appicable here as well)
Drive shafts marked 1,2,3,4,A & B in the above figure to be cleaned with acetone
Clean foil-waste-removal brushes
Clean waste rewinding shafts and release spring tension in transfer direction
Lubricate all sliding parts and bearings of the chase turning table
Remove all teflon foil C guides, to ensure proper cleaning of non-rotating, special coated shaft in platen inlet and platen outlet
Apply thin coat of oil on metal plate, opposite to the foil break sensor in platen inlet

Delivery unit

Delivery sheet brake control cams need to be cleaned and lubricated with thin layer of oil
Lubricate delivery pile supporting chain with oil
Lubricate sheet brake format adjustment rack and pinion
Grease delivery OS/DS joggers nipples and lubricate sliding jogger shaft with thin coat of oil

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
