Heat Treatment for Aluminum Castings

What is Heat Treatment? After aluminum cools in the casting process, it is engrained with specific “as cast” strength characteristics. Most applications require aluminum castings to have different mechanical properties, metallurgical structure or tensile strength that an aluminum casting will not have “as cast”. Heat treatment is used to strengthen and improve the structure of… Read more »

Smooth Surface Finish

With certain applications the surface finish of a part needs to be visually appealing. A good looking part is often seen as a sign of a high quality component. A casting with a baseline smooth and uniform surface, such as V-Process castings, will require less cleaning, finishing and machining to produce. When comparing different surface… Read more »

Shot Blaster Upgrade

As an on going effort to improve TPi’s capabilities we have recently upgraded our shot blaster with a Viking SHY4848 Spinner Hanger Y-Track Blaster. The Y-Track spinner hanger allows for easy loading and unloading of larger castings. These castings spin around a central axis allowing all sides to be blasted by the VK PowerMax 1500… Read more »

Why is draft not necessary in V-Process?

Most casting processes, such as die, permanent mold or sand casting, require a draft angle or taper to the part (die or permanent mold) or pattern (sand). The purpose of a draft angle is to allow clearance for the pattern and/or part to eject smoothly from the mold. If a mold wall is perpendicular to… Read more »

Billet Machining vs V-Process

TPi Arcade has substantial experience in converting aluminum billet parts to V-Process sand cast parts. A V-Process sand casting conversion offers minimal compromise on finish or shape. Initially, companies often chose billet machining for its net shape precision, minimal tooling dollars and short lead times. It can be a cost effective option at lower quantities…. Read more »
