Overview

Flexplate Assemblies

AmTech International is a trusted manufacturer of flexplate assemblies for OEM customers worldwide. Flexplates are typically produced using two main methods: stamping and billeting. In the stamping process, sheet metal is formed into the net shape and the ring gear is welded on. Billeted flexplates are machined from a solid metal block—either with the ring gear welded on or as a fully integrated, one-piece assembly.

Stamped flexplates are most common for standard applications. Two-piece billeted flexplates, featuring a thicker and more robust center plate, are preferred for higher horsepower and demanding environments. The strongest option is the one-piece billet flexplate, which integrates the ring gear and plate as a single, solid component for maximum durability.
Leveraging a robust global supply chain, AmTech International ensures reliable, on-time delivery of flexplate assemblies—even for large-volume orders. Our commitment to innovation, quality, and customer satisfaction makes us a preferred partner for OEMs seeking precision and reliability.

Applications

Flexplate assemblies are essential for automatic transmission vehicles, where they replace the traditional flywheel. The flexplate connects the engine’s crankshaft to the torque converter, transmitting engine rotation to the transmission and ultimately to the drive wheels. This assembly is critical for starting the engine and enabling smooth power transfer throughout the drivetrain.
AmTech offers complete in-house manufacturing capabilities for flexplate assemblies, supporting automotive and torque converter applications with precision and efficiency.
