Brake Lining Long Block Mold
The Brake Lining Long Block Mold makes long, tile - shaped brake linings. It's mainly used for hot press forming brake linings in drum brake systems of heavy - duty and passenger vehicles.
Users can get custom - designed single - layer molds with two or three cavities.
These long block brake linings work in certain braking systems, like those of construction machinery and large commercial vehicles. Their shape and durability are key to good braking performance.
Structural Features
The mold primarily consists of the upper die, lower die, and side die:
--The upper and lower dies form the main compression cavity, conforming to the top and bottom surfaces of the brake lining.
--The side dies help shape the sides of the brake lining, ensuring that the width and edge profiles meet the required specifications.
--The upper die applies pressure through hydraulic systems, working together with the lower and side dies to compress the material within the mold cavity.
Cavity Design:
The internal structure of the cavity is carefully engineered for optimal performance. Features such as micro-grooves or surface textures may be included to:
--Improve friction with the brake drum,
--Facilitate heat dissipation,
--Assist in discharging wear debris during braking.
Performance & Characteristics
* Made from 40Cr alloy steel, forged and heat-treated to a hardness of 40–55 HRC.
* Chrome plating thickness: 0.03–0.05 mm, providing excellent wear resistance.
* Includes components such as: upper/lower molds, liner, baffle, templates, drag rods, and guide sleeves.
* Mold plates are precision-ground for high accuracy.
* The gap of the hot-pressed brake lining is controlled within 0.15 mm, with a thickness tolerance of ±0.3 mm.
* Known for simple operation, high efficiency, and stable quality output.
* Especially suitable for manufacturers with high performance and quality standards.
