Zinc Collars Offering Dual Protection To Propeller Shaft Areas - The Practical Answer To Electrolysis

Due to structural limitations some boat owners prefer to use Zinc Collars which clamp directly over the boat's prop shaft. Zinc Collars are available in Standard and Slim sizes - see graphics below - depending on the size required. The collars are easily mounted and secured by sturdy stainless steel bolts.

Another popular choice in Zinc Casting is the Rudder Disc. The Rudder Disc attaches to any point on the boat's rudder blade and affords the usual efficient electrolysis protection.

Alternatively, you can use the Zinc Plate which attaches to the rudder, whereas the Disc goes to the blade.

Technical Specifications:

Zinc Collars - Standard are available in 1.75" • 2.0" • 2.25" • 2.5" sizes

Zinc Collars - Slim are available in 1.0" • 1.125" • 1.25" • 1.375" • 1.5" sizes

Zinc Rudder Discs are available in 3.0" • 4.0" • 5.0" sizes

Larger Zinc Collars are available as a special order

POROSITY SEALING

Castings Impregnating
An efficient and affordable casting porosity sealing service for foundries and die casting companies to ensure that their castings can be subjected to high pressure use within their applications.

The majority of today's castings are fine and totally suitable for regular machinery use. However, when they are subjected to high pressures, their porosity (permeability) causes them to leak. This also tends to lead to sub standard efficiency and deterioration of the application being operated.

Such castings can be found in today's high-efficiency diesel and gas powered engines, generators, transmissions, valves and other such components that operate in high pressure situations that produce huge pressure surges at start-up before returning to normal operating pressures.

Impregnating your castings is the answer.
Casting impregnation is a process that seals the porosity and permeability defects in the castings causing them to resist high pressure liquids and gases during their normal course of operation. Using a specially selected impregnating sealant, the castings are subjected to a vacuum pressure treatment which forces the sealant into the castings and eventually fills the porous voids to produce impregnated castings suitable for high pressure liquid and gas use.

Here are some of the tremendous benefits of Casting Impregnation & Sealing:

        Enjoy increased quoting opportunities.

        Allows you to offer sealed castings as an OEM product.

        Add high-pressure-ready sealed castings to your product line.

        Gives you the opportunity to pursue other lucrative markets - engine and machinery makers.

        A great opportunity to offer superior quality castings at little extra cost.

        And so much more.

Affordable & Cost Effective
As the majority of today's castings are produced with expensive tooling equipment it is not always cost effective, or even possible, to introduce impregnation to the process. The solution is to produce your castings in the normal way and have them impregnated as a separate post-process.

Crab Pot Anodes

Crab Pot Anodes are produced using a highly efficient aluminum alloy of zinc, indium and aluminum. These elements (metals) are very specific in their composition thus affording the very best in corrosion protection.

Used mainly in the commercial crabbing side of the fishing industry, these Crab Pot Anodes provide excellent protection properties against the process of electrolysis on large crab pots.

Crab Pot Anodes contain a built-in steel strap which protrudes from either end of the aluminum casting and is welded to the framework of the crab pot.

Crab Pot Anodes are cast in an open metal mold - similar to permanent mold - and are cast in large quantities ensuring they are usually in stock at all times.

We cast a single standard size that incorporates the built-in steel strap.

Technical Specifications:

Construction: Aluminum, Zinc & Indium Alloy with built-in Steel Strap

Crab Pot Anode Length - Including Steel Strap Protrusion = 15.75 inches

Crab Pot Anode Length - Without Steel Strap Protrusion = 11.5 inches

Crab Pot Anode Height = 1.5 inches

Crab Pot Anode Width  = 2.0 inches

HEAT-TREATMENT

Do Your Castings Need Extra Strength & Machinability?

Look no further!

You have found one of the best heat treating facilities for metal castings.

Now you can add the necessary treatment to produce a superior casting with all the properties required for high strength and age hardened casting products.

Here are some of the tremendous benefits to using our heat treat service:

• Apply extra strength and hardness to aluminum alloys.
• Enhance the machinability of your castings.
• Reduce metal fatigue.
• Tempering to T-4, T-5, T-6, T-7, T-51 & T-61.
• Rapid quenching and age hardening.
• Fastest turnaround as we heat treat in-house.
• Add high strength castings to your product line.
• Affordable & Cost Effective

As the majority of today's castings are produced with expensive tooling equipment it is not always cost effective, or even possible, to introduce heat treating into your process. The solution is to produce your castings in the normal way and have them heat treated by us as a separate post-process.
