Zastata uses a variety of materials for Plastic Injection moulding process to produce various types of products.The plastic used in the injection moulding process is typically a thermoplastic, composed of polymers, resins, and other materials each with its own advantages and disadvantages. The kind of material used to mold the part mainly depends on its application and utilization.

Plastic Injection moulding can be performed with a wide variety of materials, including different types of plastics, elastomers, nylon, rubbers, and most commonly thermoplastic and thermo setting polymers.


Thermoplastics, malleable polymers, are melted and moulded to create parts, and their reusability for various shapes makes them invaluable in injection moulding processes.

Thermo setting Polymers

Thermosetting polymers cure under heat or pressure, ensuring their shape and strength, making them ideal for high-heat applications like engine parts.

Amorphous plastics

Plastics like ABS, PS, acrylic, and polycarbonate have a broad melting range, resulting in minimal expansion or shrinkage when exposed to temperature changes.

Semi-Crystalline Plastics

Unlike amorphous plastics, PP, PE, nylon, and POM have sharp melting points, resulting in predictable expansion or shrinkage with temperature.

Mold components require thorough inspection due to their intricate parts and sensitive structure. The injection moulding machine must be inspected to ensure that all its components are functioning properly. It is essential to perform regular inspection through the process.

Zastata also performs number of inspection methods to ensure parts are made as per drawing.

The most common inspection methods are visual inspection, X-ray inspection, and ultrasonic inspection.

  1. Visual Inspection: Visual inspection is the simplest and most common inspection method and can be used to identify a wide range of defects. However, it is also the least accurate method, and can be affected by lighting and operator error.
  2. X-ray inspection: This is more accurate than visual inspection and can be used to identify defects that are not visible to the naked eye. However, it is more expensive and requires specialised equipment.
  3. Ultrasonic inspection is the most accurate inspection method and can be used to identify a wide range of defects. However, it is also the most expensive method, and requires specialised equipment.

By regularly inspecting parts and detecting any flaws prior to use, Zastata can ensure that their components meet the desired quality and help them produce reliable components for a variety of industries.

Other Types of Casting

Whilst Pressure die casting is a widely used casting method for high-volume production, there are other casting methods that have their merits


Plastic injection moulding is a manufacturing process used in variety of industries with greater design flexibility.

  • In the medical industry, plastic injection moulding is used to create components for diagnostic equipment and medical devices, including needles and tubing, blood filters, and drug delivery systems, etc.
  • In the automotive sector, injection moulding is used to produce countless components, such as wheel covers, trim, seatbelts, battery cases, airbag components and antenna covers.
  • It is also used to create electrical components and machine parts, as well as toys, sporting equipment and consumer electronics.

Plastic injection moulding [PIM] is a complex process with multiple stages that requires using a variety of materials. These materials range from the injection moulding machine and clamps to the molten plastic, moulds, and assembly and testing equipment.

Zastata ensures that parts manufactured by our manufacturers using this process are 100% compliant to the design spec and are inspected 100% for pilot production runs to ensure quality components are exported without any defects.
