Established in 1995
Plastic Auxiliary Machines Manufacturer in India
From material drying and feeding through to mixing, temperature control and scrap recycling, we design and build the auxiliary machines that keep an injection moulding, extrusion or blow moulding line running. Fifteen machine models across five categories, fabricated and wired at our own plant in Rajkot and supplied to moulders, extruders and recyclers across India.

Our machine range
Plastic Auxiliary Machines We Manufacture
Machine models across five categories. Select a category to see the machines built for that stage of your line. Every machine on this page is built in-house. That is the practical difference between us and most plastic auxiliary machines manufacturers in India.
Plastic Hopper Dryers
Dry hygroscopic and non-hygroscopic granules before they reach the barrel, removing moisture that causes splay marks and weak weld lines.
Capacity
12–600+ kg
Drying temperature
up to 180°C
Drying Loaders
Combine a hopper dryer and a vacuum loader in one unit, delivering dried granules to the machine hopper in a single continuous step.
Capacity
25–300 kg
Footprint
Reduced vs two units
Euro Loaders
Compact loader mounted directly on the machine hopper, pulling granules from a nearby box or bag without a separate control panel.
up to 100 kg/hr
Direct on-hopper
Vacuum Hopper Loaders
Pull granules, regrind or masterbatch from bags, boxes or a central silo straight into the machine hopper.
up to 300 kg/hr
Stainless steel
Multi Station Hopper Loaders
One vacuum pump feeding several machine hoppers in sequence, cutting the number of loaders needed on a multi-machine line.
Central Control Station
Manage material routing and drying status for multiple machines from a single centralized control point.
Control
Central Material Distribution Station
Route different materials from multiple silos to the correct machine through a valve manifold, without manual switching.
Outlets
up to 12
Control
PLC-sequenced valves
Vertical Batch Mixer
Blend virgin resin with masterbatch, additives or regrind in a set ratio before it reaches the hopper.
Batch size
Control
Vertical Conical Mixer
Blends in a tapered vessel that empties fully with no dead corners, suited to frequent colour or material changeovers.
Batch size
15–300 kg
Vessel
Volumetric Dosers
Meter a fixed proportion of masterbatch or additive into the material stream by volume, for lines that don’t need a full mixer.
Dosing ratio
Mounting
Mould Temperature Controller
Hold the mould surface at a set point independent of the chiller loop, keeping part finish and cycle time consistent shot to shot.
Industrial Chiller
Circulate chilled water to mould, barrel and hydraulic circuits, holding temperature steady as ambient conditions change.
Low-speed Granulator
Reduce large sprues, runners and rejected parts with a slow-turning rotor, running quietly with less dust and heat build-up.
Wide, for bulky parts
Plastic Scrap Grinder
Granulate sprues, runners and reject parts into uniform regrind that blends straight back into virgin material.
50–500+ kg/hr
4–10 mm
Plastic Flake Cutter
Slice film, sheet offcuts and washed flake to a uniform size for consistent feeding into extrusion or recycling lines.
6–14 mm
Why Seaways Machinery
Built and Backed by the Same Team
Fabricated in-house, not bought in
Design, sheet metal fabrication, assembly and panel wiring happen under one roof, so tolerances and after-sales support stay in our control.
Sized to your line, not a model number
Capacity, heater load and controls are specified against your actual material throughput and plastic type, not a fixed catalogue size.
Installed and commissioned on site
Our engineers travel to your plant to install, wire and run the first production batch alongside your operators before handover.
Spares held for fast turnaround
Heater elements, thermocouples, blower motors and control boards are stocked, so a breakdown doesn't stop your line for long.

Common Questions
Frequently Asked Questions
What are plastic auxiliary machines?
Auxiliary machines are the support machines that work around an injection moulding, extrusion or blow moulding machine. They dry the granules, feed them into the hopper, mix in masterbatch, control mould and water temperature, and grind scrap back into usable regrind. The main machine makes the part; the auxiliary machines keep it running properly.
Which auxiliary machines does Seaways Machinery manufacture?
As one of the plastic auxiliary machines manufacturers in India building across all five categories, we make 15 machine models models across five categories: drying (hopper dryers, drying loaders), feeding and conveying (euro loaders, vacuum hopper loaders, multi-station loaders, central material distribution), mixing and dosing (vertical batch mixers, conical mixers, volumetric dosers), heating and cooling (mould temperature controllers, industrial chillers) and granulating and recycling (low-speed granulators, scrap grinders, flake cutters).
Are you a manufacturer or a trading company?
We are manufacturers. Design, sheet metal fabrication, assembly and control panel wiring all done at our own plant in Rajkot, Gujarat. We control build quality, we can change a design to suit your line, and the same team that built the machine also services it.
Can I get all the machines for one line from you?
Yes. Most customers start with one machine and come back for the rest, but you can source the full set. Dryer, loader, mixer, mould temperature controller, chiller and grinder, from a single supplier. One point of contact, one set of documentation, matched capacities across the line, and one number to call if something stops working.
How do I know which size or capacity I need?
Tell us your material (PP, PET, ABS, nylon and so on), your consumption in kg per hour, and the machine it will feed. We size the capacity, heater load and controls against your actual throughput, not a fixed catalogue model. Sending a photo of your existing setup also helps us suggest the right loader or mixer.
What do plastic auxiliary machines cost?
Price depends on capacity, insulation, material of construction and the type of controls you choose (analog or PLC). A small loader and a large chiller are priced very differently, so we quote per machine rather than give a single rate. Share your material and throughput on +91 99987 22228 or info@seawaysmachinery.com and we will send a written quotation with GST and delivery included.
Do you supply plastic auxiliary machines across India?
Yes, we supply moulders, extruders and recyclers across India from our Rajkot factory. Standard models are usually dispatched shortly after order confirmation. Custom-built machines take longer. GST invoicing, e-way bills and transport documentation are handled from our side.
Do you install the machine and support it afterwards?
Yes. Our engineers travel to your plant to install the machine, guide the electrical connections, run the first production batch with your operators and hand over only once it is running. Common wear parts such as heater elements, thermocouples, blower motors and control boards are kept in stock so a breakdown does not hold up your line. Annual maintenance contracts are available on request.
Can you build a machine to my specific requirement?
Yes. Beyond our standard range we build non-standard capacities, special temperature ranges, machines for a particular plastic and custom control panels. Because we are one of the few plastic auxiliary machines manufacturers in India doing fabrication and panel wiring in-house, a special requirement is a build change for us. Custom builds usually take a few weeks from order confirmation.
