End Cover Low Pressure Casting For General Mechanical Components
This End Cover serves as a bearing retention and sealing interface on general mechanical assemblies, rotating shaft systems, and industrial equipment housings. Weighing approximately 1.2 kg with overall dimensions of 80 × 120 × 65 mm, it is produced through our in-house low-pressure die casting + CNC precision machining route. A356 aluminum alloy, T6 heat-treated, gives this cover the combination of strength, pressure tightness, and lightweight characteristics needed for shaft-end applications.
Matech's one-stop approach, covering mold design, low pressure die casting, T6 heat treatment, CNC machining (bearing bore, sealing face, mounting holes, oil seal seat), leak testing, shot blasting, dimensional inspection, and engineered packing, ensures this end cover offers excellent bore-to-face perpendicularity, tight dimensional tolerances on sealing and mounting interfaces, and a ready-to-assemble finish — performing reliably in general mechanical drive applications.

Our Advantages
Technical Advantages
From mold fabrication and low pressure casting to T6 heat treatment, CNC machining, leak testing, and shot blasting — every step is handled inside our facility. This means no hand-offs between vendors, no waiting on external schedules, and a single quality standard applied from the first casting to the final packed cover.
Before mold production, our engineers review the end cover design for filling behavior, shrinkage risk around the bearing hub, and wall thickness transitions between the flange and the shaft bore. The result is a casting that machines cleanly and holds tolerance without surprises.
End covers are unforgiving on perpendicularity and bore accuracy. Our low pressure casting line, combined with 3/4-axis CNC machining and dedicated fixtures, holds the bearing bore and sealing face within tight perpendicularity limits — a key requirement for quiet, leak-free shaft rotation.

Material Advantages
Every batch of A356 ingot is checked by spectrometer before melting, and the melt is re-verified before pouring. We adjust silicon and magnesium levels in real time to keep the alloy within ASTM B26/B26M specification — the foundation for consistent T6 response and uniform hardness after heat treatment.
Each production lot carries a unique heat number. The dossier includes ingot certificate, spectrometer analysis, T6 time-temperature curve, hardness test results, and final dimensional report — all linked back to the raw material batch.
While A356 with T6 is the standard choice for end covers requiring strength and pressure tightness, we also cast A380, ADC12, ZL101, and ZL102. If your application calls for higher wear resistance or better machinability, we can recommend the right grade and adjust casting parameters accordingly.
Service Advantages
A single project manager tracks your end cover from drawing review through mold making, sampling, batch production, and shipment. You get one contact, one schedule, and one point of accountability.
Quotations typically go out within 24–48 hours. Before mass production, we supply a first-article inspection report covering bore perpendicularity, sealing face flatness, mounting hole position, and material certification — so you can approve with confidence.
Batch traceability, mold maintenance records, and 24-hour response to quality issues keep your production line supplied without interruptions. Pilot orders and flexible MOQ are available for new end cover projects.
