At Dhanya, Injection moulding machines are available in a wide range of sizes till 400MT to accommodate different production needs and part dimensions. The size of a Injection moulding machine is primarily defined by the shot weight, which dictates the maximum out put of the plastic material can be processed. Dhanya has different moulding machines sizes ranging from 90MT, 120MT, 200MT, 380MT & 400MT for all industry needs.
Injection Moulding – High Precision Plastic Manufacturing
Injection Moulding is one of the most efficient and versatile manufacturing processes used to produce complex and high-quality plastic components with exceptional accuracy. The process involves injecting molten thermoplastic or thermosetting material into a mould cavity under controlled pressure, allowing manufacturers to create durable, consistent, and cost-effective products at high volumes.
From automotive parts to consumer electronics, medical equipment, packaging solutions, industrial components, and household products, Injection Moulding delivers unmatched precision, repeatability, and scalability.
Why Injection Moulding?
High Precision & Accuracy Injection Moulding produces parts with tight tolerances and perfect detailing, making it ideal for industries requiring exact specifications.
Cost-Effective for Mass Production
Once the mould is created, thousands or even millions of identical parts can be produced at a very low cost per unit.
Excellent Surface Finish
Injection-moulded components offer smooth, ready-to-use surfaces without the need for heavy post-processing.
Wide Material Selection
Compatible with various materials such as
- PP (Polypropylene)
- ABS (Acrylonitrile Butadiene Styrene)
- HDPE, LDPE
- Nylon (PA)
- Polycarbonate
- PVC
- Thermoplastic Elastomers (TPE)
Strength, Durability & Consistency
Each part manufactured through injection moulding maintains consistent quality, mechanical strength, and performance.
Supports Complex Shapes
The process can easily create intricate designs, thin walls, undercuts, ribs, and custom geometries that are difficult to achieve with other methods.
Injection Moulding Process
- Material Feeding
Plastic granules are fed into the injection moulding machine hopper. - Melting & Plasticizing The material is heated until it becomes molten.
- Injection The molten material is injected into the mould cavity under high pressure.
- Cooling The mould cools down, allowing the plastic to solidify and take shape.
- Ejection Once cooled, the mould opens and ejector pins release the finished part.
Applications of Injection Moulding

- Automotive dashboards, bumpers, clips, and interior parts
- Electrical housings, switches, and connectors
- Medical devices and components
- Packaging products and containers
- Toys, household items, and hardware
- Consumer electronics (remote casings, chargers, handles)
Specialized Applications

Frequently Asked Questions
PEEK (Polyether Ether Ketone), known for high heat resistance, strength, and chemical stability in demanding applications.
A process where two materials (e.g., plastic and rubber) are molded together to create multi-material parts like ergonomic grips.
- Injection Moulding: Faster and cheaper for 1,000+ units.
- 3D Printing: Better for prototypes and small batches (<100 units).
Yes, when using recyclable plastics or biodegradable polymers. Excess material can often be reground and reused.
Look for these signs:
- Parting lines: Seams where mold halves meet.
- Ejector pin marks: Small circular impressions on the part.
- Gate marks: Entry points where molten plastic was injected.
- Uniform wall thickness: Optimized for structural integrity.
The four key stages are:
- Clamping: The two halves of the mold are securely closed.
- Injection: Molten plastic is injected into the mold cavity.
- Cooling: The material solidifies as it cools.
- Ejection: The finished part is ejected from the mold.
Typically 8–16 weeks, depending on mold complexity (steel vs. aluminum) and design requirements.
High efficiency, low per-unit costs for large volumes, and consistent quality with minimal material waste.
Automotive, aerospace, medical, consumer electronics, packaging, and construction for parts like housings, gears, and connectors.
Common materials include thermoplastics (ABS, PP, PC, Nylon), elastomers (TPU), thermosets, and metals (via Metal Injection Moulding).
A manufacturing process where molten material (plastic, metal, or silicone) is injected into a mold under high pressure to produce identical parts at scale.
