Used welding machinery for injection moulding

A welding machinery is thermoplastic processing equipment used to weld and join polymers into finished or semi-finished products. Injection moulders, extrusion companies, blow moulders, and thermoforming shops operate these machines. Buying used welding machinery is common because plastic processing machines from brands like Arburg, KraussMaffei, Engel, Battenfeld, Demag retain precision over long service lives, and retrofit options are widely available.

Types and applications of used welding machinery

Different welding machinery configurations serve different production requirements. Choosing the right type depends on your material, volume, and quality targets.

MIG/MAG welders

MIG/MAG welders use a continuously fed wire electrode with shielding gas. Fast, productive, and suitable for steel and aluminium.

TIG welders

TIG welders use a non-consumable tungsten electrode with separate filler wire. Produce high-quality, clean welds on thin materials.

Resistance welders

Resistance welders pass current through overlapping sheets to create spot, seam, or projection welds. Common in automotive body production.

Plasma cutters

Plasma cutters use ionised gas to cut conductive materials. Faster than oxy-fuel on thin and medium plate.

Laser welders

Laser welders concentrate energy in a fine beam for deep, narrow welds with minimal distortion. Ideal for precision assemblies.

Key technical parameters of used welding machinery

Evaluating a used welding machinery requires understanding specifications that determine compatibility with your production requirements.

Welding current range

Welding current range in amperes determines the thickness of material that can be joined. MIG welders typically offer 30–500 A.

Duty cycle

Duty cycle is the percentage of a 10-minute period the machine can weld at rated current without overheating. Industrial units offer 60–100% at maximum amperage.

Wire diameter

Wire diameter affects deposition rate and weld bead profile. Common sizes are 0.8–1.6 mm for steel and 1.0–1.2 mm for aluminium.

Welding processes (mig/tig/mag)

MIG/MAG uses continuous wire feed for fast production; TIG offers precise, clean welds on thin materials. Verify process compatibility with your applications.

Cooling system

cooling system is a critical specification that determines machine suitability for your application. Verify against your production requirements.

Torch type

torch type is a critical specification that determines machine suitability for your application. Verify against your production requirements.

Buying checklist for used welding machinery

Inspecting a second-hand welding machinery before purchase reduces the risk of hidden defects and costly downtime. Use the following checklist during evaluation.

• Inspect mechanical components for wear, cracks, and unauthorised repairs.
• Check bearings for radial and axial play, unusual noise, and overheating during test runs.
• Verify electrical cabinet condition, safety circuits, and emergency stop functionality.
• Confirm voltage, frequency, and phase compatibility with your facility supply.
• Review maintenance logs, service invoices, and previous operating environment.
• Test all control functions including start, stop, speed variation, and safety interlocks.
• Assess spare parts availability and lead times for the specific brand and model.
• Request a trial run with your typical material, speed, and load conditions.

Typical industries and use cases

Used welding machinery serve a wide range of industrial sectors. The following industries represent core demand on the European secondary machinery market.

• Injection moulding: Production of plastic parts by injecting molten polymer into moulds.
• Extrusion: Continuous production of profiles, pipes, films, and sheets.
• Blow moulding: Manufacturing of hollow containers, bottles, and tanks.
• Thermoforming: Vacuum and pressure forming of sheet plastic into trays, blisters, and shells.
• Recycling: Sorting, shredding, washing, and reprocessing of post-industrial and post-consumer plastics.

Buying used welding machinery instead of new machines delivers immediate cost reduction, shorter delivery times, and proven mechanical reliability. Industrial equipment from Germany, Austria, Italy, EU is engineered for long service life, making the secondary market a rational sourcing channel.

FAQ: used welding machinery

What is a welding machinery and what is it used for?

A welding machinery is industrial equipment used to weld and join in manufacturing environments. It serves production facilities, workshops, and processing plants across multiple sectors. Key selection criteria include capacity, precision, power requirements, and compatibility with your existing workflow.

How much can I save by buying a used welding machinery?

Savings on the secondary market typically range from 30% to 70% compared to new machines, depending on age, brand, condition, and included accessories. Premium brands retain value while still offering significant discounts.

Which brands of used welding machinery are most reliable?

Arburg, KraussMaffei, Engel, Battenfeld, Demag are widely regarded for durable construction and available spare parts. Machines from these manufacturers are common in the European used machinery market and supported by established service networks.

What should I check when inspecting a used welding machinery?

Check mechanical wear, bearing condition, electrical safety, control functionality, and dimensional accuracy. Run the machine under load if possible and request maintenance records, manuals, and wiring diagrams.

Is it safe to buy a used welding machinery without seeing it in person?

Risk can be minimised by requesting detailed photos, video of the machine running under load, maintenance records, and third-party inspection reports. WeSellMachines.com provides documented listings and direct seller communication.

Can a used welding machinery be integrated with modern production systems?

Many used machines support standard interfaces and file formats. Verify the control model, available communication protocols, and software compatibility before purchase. Retrofit options are often available.

What is the typical power supply requirement?

Industrial machines usually require three-phase 400 V / 50 Hz supply. Confirm that your facility can deliver the required amperage and has appropriate circuit protection and earthing.
