Product Overview
The Automotive Brake Caliper houses and supports the components responsible for applying clamping force to the brake pads. During braking, the caliper works with the brake pads and disc to generate the friction required to slow the vehicle. Its housing must accommodate the specified internal cavities, mounting points, and machining interfaces while maintaining the structural integrity required by the braking system. Dimensional consistency is particularly important around mounting surfaces and other features that affect caliper assembly and alignment.
Sangroove (Jiangsu) Machinery Co., Ltd. manufactures automotive brake caliper and caliper housing castings for a range of vehicle applications. The production requirements are defined according to the component drawing, selected material, and intended operating conditions. QT500 and QT600 ductile iron are listed material options, while high-strength cast steel and alloy steel may be considered where supported by the customer's design specification.
Depending on the part geometry, manufacturing may involve green sand casting or shell mold casting, followed by specified heat treatment and CNC machining. Machining operations can address designated mounting faces, holes, and other interfaces required for brake system assembly. Material verification, hardness evaluation, mechanical testing, and dimensional inspection can be incorporated into the agreed quality plan. Customers can submit 2D drawings or 3D models to review casting feasibility, machining scope, surface protection, and inspection requirements before production.
