Dies And Mould For Extrusion Lines
Introduction
Welcome to Kriimpas India Pvt. Ltd., where we offer comprehensive solutions for all your material processing needs. Since 2012, we have been dedicated to providing top-notch machinery and services to our valued customers.
The effectiveness of an extrusion process in the production of plastics and polymers depends as much on the equipment’s quality as it does on the raw material. The dies and moulds, which are the precise tools that eventually shape molten plastic into pipes, sheets, films, profiles, or intricate bespoke shapes, are at the centre of this apparatus.
Selecting the appropriate dies and moulds is essential for businesses seeking dependability, consistency, and high precision. We at Kriimpas India Pvt. Ltd. are aware of how important moulds and dies are to any extrusion process. To provide the best performance, consistency, and quality for a range of applications, our extrusion lines combine top-of-the-line extruder machines with precise dies and moulds. We are the best Dies And Mould For Extrusion Lines Manufaturer.
What Are Extrusion Dies and Moulds
Extrusion creates a continuous profile by melting raw materials such as plastic pellets, powder, or other polymer blends and forcing them through a die. The cross-sectional shape of an extruded profile, such as a pipe, tube, window profile, sheet, or any unique design, is defined by a die. Additionally, a mould may be used in extrusion-based processes, particularly in hybrid extrusion-injection setups, or when the extruded product is being finished or shaped while it cools.
The shape, quality, and consistency of final products are therefore largely dependent on the die and mould set, which forms the core of an extrusion line. Inadequate tooling can result in waste, downtime, uneven dimensions, and defects. We are the best Dies And Mould For Extrusion Lines Supplier.

- Conduit tubes for electrical wiring or cable protection — requiring smooth internal/external surfaces for easy cable pulling.
2. Window/Door Profiles & Architectural Extrusions
- Profiles for doors, windows, frames — especially in uPVC or PVC — where surface finish, tight tolerances, and aesthetic quality are vital.
- Decorative profiles, skirting boards, piping covers, and conduits — extruded in plastic or composite materials.
3. Rubber Extrusions & Seals

Types of Dies for Extrusion Lines
1. Profile Dies Open Profile Dies
- Used to extrude complex cross-sections (window frames, gaskets, channels). Profile dies are designed to control flow path so material fills the profile evenly, avoiding warpage and ensuring uniform wall thickness.
2. Flat Sheet Board Dies
- Flat dies produce sheets, boards, and wide profiles. Important design aspects include manifold distribution and lip design to ensure an even melt front and uniform thickness across the width.
3. Slot Dies
- Used for coating and laminating as well as for producing very thin films or layers with precise thickness control. Slot dies are prized for uniformity in thickness and low variability.
4. Pipe and Tube Dies Annular Dies
- Designed to create circular cross-sections such as pipes, tubes, and hoses. They focus on concentric flow and often are paired with calibrators and vacuum tanks to maintain roundness and dimensional stability.
5. Multi-layer Co-extrusion Dies
- Used when producing layered structures (barrier films, composite pipes). These dies have multiple feed channels and a feedblock system to combine melts into a single, bonded multilayer product. Precision control of layer thickness and adhesion is critical.
6. Strand Dies
- Common in pelletizing and where multiple small profiles are extruded simultaneously (e.g., for cutting into pellets). Strand dies must ensure consistent strand spacing and flow to prevent variations.
