Bracket Steel Casting Investment Casting (Lost Wax) For Transmission Equipment
This Steel Bracket Casting is a core structural and load-bearing component designed for transmission equipment, mechanical drive assemblies, and industrial power transmission support structures. Weighing approximately 1.6 kg, it is manufactured by our in-house Investment Casting (Lost Wax) + CNC precision machining process to achieve high strength, precise mounting geometry, and reliable structural integrity. The use of cast steel ZG45 provides an excellent balance of high tensile strength (≥450 MPa), superior impact toughness, and excellent fatigue resistance under cyclic loading.
Matech's one-stop approach, covering wax pattern making, investment casting, annealing/normalizing heat treatment, CNC machining (mounting faces, dowel holes, threaded holes, locating slots), dimensional inspection, surface treatment (Dacromet coating), and engineered packing, ensures this bracket offers excellent mounting interface accuracy, tight dimensional tolerances on locating features, and a ready-to-install finish — performing reliably in demanding transmission equipment applications.

Our Advantages
Technical Advantages
Wax pattern shop, investment casting line, CNC machining workshop, heat treatment furnaces, surface treatment, and inspection lab — all centralized under one roof. No outsourcing. From molten steel to finished and coated part, we maintain full control over lead time, quality consistency, and batch traceability.
Before wax pattern production begins, we provide a detailed DFM report covering solidification behavior, shrinkage analysis, gating & riser design, and machining allowance optimization. For investment cast brackets like this 1.6 kg ZG45 component, we focus on wax pattern dimensional stability, shell build-up strategy for fine surface detail, and riser placement to ensure sound metal in load-bearing sections.
We specialize in precision steel castings with complex geometries and fine surface detail — such as brackets, transmission components, linkage parts, and mechanical mounts. Our investment casting process delivers superior surface finish, tight dimensional tolerances, and the ability to form intricate shapes with minimal machining allowance. We pour a full range of cast steels — ZG45, ZG35, ZG55, stainless steel, and alloy steel — with in-house heat treatment to tailor strength, hardness, and toughness to your specification.
Service Advantages-总部接待区 1 拷贝
Material Advantages
We charge carefully sorted steel scrap and certified ferroalloys into our electric induction furnaces. Every heat is chemically analyzed by spectrometer before tapping, with real-time adjustments to carbon, manganese, silicon, and alloying elements. Deoxidation practices ensure clean steel with low inclusion content — critical for maintaining consistent ZG45 mechanical properties in thin-walled investment castings.
Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (tensile strength, yield strength, elongation, hardness, impact toughness), and heat treatment charts are compiled into a traceable dossier — from furnace charge to finished bracket.
We pour a comprehensive range of cast steels — carbon steel (ZG35/ZG45/ZG55), low-alloy steel, stainless steel (304/316/CF8/CF8M), and duplex stainless steel. Whether your application demands impact toughness for transmission loads, wear resistance for mechanical contact, or corrosion resistance for aggressive environments, we match the grade and heat treatment to your requirements.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For investment cast parts, first-article inspection reports including dimensional layout and material certification are provided before batch production begins.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new investment casting projects.
