What Is Flat Die?

An extruder flat die is a specialized component used in various extrusion processes, The die shapes the molten material as it exits the extruder, allowing it to spread into a flat profile. The extruder flat die plays a crucial role in the extrusion process, enabling manufacturers to create flat products with precision and efficiency.

Key Features of Flat Dies:

Design: Typically features a long, rectangular shape that allows for uniform distribution of the material.

Flow Channels: Includes flow channels that help control the rate and direction of the molten material, ensuring even thickness.

Adjustability: Some flat dies offer adjustable gaps to accommodate different thicknesses and material types.

Cooling: Often paired with cooling systems to help solidify the material quickly after extrusion.

Advantages:

Uniform Thickness: Helps achieve consistent product dimensions.

Versatility: Can be used with various thermoplastics and other materials.

Efficiency: Enhances production speed and reduces waste.

Shanbao's Flat Die

We have three materials for the flat dies to meet the customer’s need for toughness and abrasion performance.

We chose high-strength steel as the raw material and made a special wear-resistant process to get the special wear-resistant layer and surface hardness that can reach HRC 70. This kind of high-strength steel has high impact toughness and strong fracture resistance in the internal. And internal hardness can reach HRC 55.

The normal flat die is also made of high-wear resistance mold steel for prolonged usage, with maximum cutting and scraping resistance.

The product also uses a machining center to obtain smooth discharging, small diameter error, and high mold hole finish.

Type

We have several types of holes, such as long cones, short cones, stepped, and arcs to meet the different expansion requirements.

A small angle deep cone is suitable for the formula that multi-fiber easy to block the holes.

A spherical arc is suitable for less starch formula.

A big angle is suitable for less expansion feed.

We can make the hole designs based on your formula and feed. To help you get the maximum throughput.
