Welcome to our blog for insights into different manufacturing processes.
Introduction Shell quality is the defining variable in investment casting that determines surface finish, dimensional accuracy, defect incidence and downstream cleaning effort. A high-performance shell must simultaneously satisfy multiple, sometimes
Surface quality of castings is a function of every step that touches the pattern, mold and metal — from die/pattern condition and pattern-material rheology through shell/facecoat preparation, dewaxing and shell
1. Executive summary Conventional (decorative) anodizing and hard (hardcoat) anodizing are both electrochemical conversion processes that produce an aluminum-oxide (Al₂O₃) layer on aluminium alloys. They share the same basic chemistry
1. Executive summary Case hardening creates a thin, very hard surface layer (the “case”) on a tougher, ductile core. It combines surface wear and fatigue resistance with a ductile core
1. Executive Summary EN-GJS-400-15 is a widely used grade of ductile (spheroidal graphite) cast iron defined under the European EN 1563 standard. A balanced combination of moderate tensile strength, high
1. Introduction Water glass investment casting (also known as sodium silicate investment casting) is a precision casting technology that uses water glass as the binder for the shell, combined with
1. Introduction CD3MWCuN (UNS J93380, ASTM A890/A995 Grade 6A) is a high-performance super duplex stainless steel (SDSS) developed in the mid-1980s, specifically engineered to address the corrosion challenges of extreme
1. Introduction Aluminum die casting is a high-efficiency, near-net-shape manufacturing process widely used in automotive, electronics, aerospace, and household appliance industries due to its ability to produce complex components with
1. Introduction CD4MCu (commonly supplied to cast-steel specifications such as ASTM A890 Grade 1A for duplex castings with UNS number J93370) is a purpose-engineered duplex stainless casting that combines high
ASTM A744 CN7M is a cast, high-nickel, molybdenum- and copper-bearing austenitic stainless alloy engineered for aggressive chemical service—notably sulfuric and other reducing acids, chloride-bearing process streams and mixed acid duties.
1. Introduction ASTM A36 is the standard specification for a low-carbon structural steel widely used for plates, shapes, bars and welded components in building and general structural applications. It is
1. Introduction Polypropylene (PP) is a semicrystalline thermoplastic polyolefin notable for low density, broad chemical resistance, and cost-effective processing. It exists as isotactic homopolymer and as several copolymer families; additives
In advanced industrial systems—gas turbines, reheating furnaces, chemical reactors and aerospace hardware—materials are routinely expected to survive extreme thermal and chemical environments while retaining strength, dimensional stability and resistance to
1. Introduction Aluminum alloys are widely cast in sand, permanent mold, die, gravity or investment processes for automotive, aerospace, consumer and industrial applications. Compared with ferrous castings, aluminum presents specific
1. Introduction Polyethylene (PE) is a polymer produced by polymerisation of the monomer ethylene (CH₂=CH₂). First commercialised in the 1930s, PE is now available in multiple engineered forms whose properties
