The short answer If the part moves against something, carries a load at temperature, or meets seawater, it is bronze. If it is a fitting, a housing, a valve body or a decorative item in a dry environment, brass will usually do the same job for less money and machine more easily. The trap is that the names do not reliably tell you which you have — see the naming section below. What bronze and brass actually are Bronze is copper alloyed with a metal that is not zinc — historically tin, and in modern practice also aluminium and silicon. Tin bronze is the bearing alloy. Aluminium bronze is the […]

鋳型製作工程そのもの：合金ごとの原型余裕、砂および結合剤の目標値、突き固めと鋳型の硬度、ゲートおよびライザーの設計、ベント、型締め、注湯温度、シェイクアウト――さらに、3Dプリントされた砂型において原型を完全に除去する場合についても解説します。.

How lost wax casting works, step by step: pattern waxes, ceramic shells, dewaxing, burnout, pouring, tolerances and the defects to watch for.

Industrial SLS pricing bands, coated sand and PSB wax consumables, laser time and a per-part worked example, with a worksheet for filling in your own local costs.

The sand casting process from pattern to finished part: six steps, five molding methods compared, sand and binder selection, gating and riser design, and pattern options.

A foundry audit that fits in one visit: the documents to request, what to watch on the floor, a 25-point scorecard, and the findings that should end the visit.

Alloy, size and tolerance set your shortlist. Annual volume picks the winner. A three-way comparison of sand, investment and die casting, with the crossover points that decide it.

Where 3D printing fits into investment casting: printed wax patterns, rapid tooling from printed masters, tooling-free prototyping, and an honest look at what it does not change.
