Foundry Chaplets

double-head-chaplets

Double Head Chaplets

Double Head Chaplets are manufactured using mild steel, generally coated with tin and used when casting a heavy metal section where the increased strength resulting from welding the chaplets is required. Non-ferrous metal such as stainless steel are available upon request.

The information listed in the chart details general characteristics on their dimensional design. These chaplets can have grooved or plain stems, perforations pierced in the plates, extensions or pins welded which protrude from the plates. The plate(s) can be curved to a specific radius. Additional design modifications can be integrated to meet your specifications.

Height can be produced from 1/4″-5,7 to 5″-127,0.

triple-head-chaplets

Triple Head Chaplets

Triple Head Chaplets can be manufactured in a variety of ways and in a range of metals. They are used in castings where two headed chaplets do not knit or fuse, creating a defect in the casting, usually porosity. By adding a third plate know as the center dam into the design of the chaplet, this feature can eliminate the defect in the casting. Pending your application we can best match the appropriate manufacturing process to suit your specifications.

Because of the various manufacturing processes these chaplets can have grooved or plain stems, perforations pierced in the plates, or extensions or pins riveted or welded which protrude from the plates. Center dams can be larger or smaller than the outside plates. They can have serrations or smooth edges. Additional design modifications can be integrated to meet your specifications. Creating a Triple Head Chaplet for your specification is based on the application required.

Separator Chaplets

separator-chaplets

Separator Chaplets are manufactured from mild steel, generally coated with tin, and used in water jacket cores in the casting of engine blocks.

Because of the variety of manufacturing processes Separator Chaplets can have the following characteristics; distance between the plates can be manufactured with round or flatten wire (stems), or one piece of mild steel that is solid or has cutouts (bodies); plates can be solid or have perforations, curved to a specific radius, and have protrusions, tab(s), wing(s), or ear(s) extending off the plates. Creating a separator for your specification is based on the application required.

 

Radiator Chaplets
radiator-chaplets

Radiator Chaplets are manufactured from mild steel, generally coated with tin and used in thin-walled castings where the chaplet can be set in the pattern or into an insert in the pattern before the mold is formed or rammed. Non-ferrous metals for the stem such as aluminum, and copper, are available upon request.

The information listed in the chart details general characteristics on their dimensional design. These chaplets can have knitting nicks, to aid in fusion, on the stems and a break-off nick above the shoulder. Their heads can be produced in a cross, square, or “SR” open configuration. Additional design modifications can be integrated to meet your specifications.

 

Core Clips
core-clips

Core Clips can be manufactured in a variety of shapes, sizes, and metals. They are used to assemble and hold core packages together. They can be used for small or large core assemblies, and normally do not require any tools during application.

Because manufacturing processes and materials used in their production allow for flexibility in design, core clips can be custom designed to meet your specifications and the requirements of your specific application.

 


Perforated Chaplets 
perforated-chaplets

Perforated Chaplets are manufactured from tin coated steel sheet or non-ferrous sheet, depending on the metal being cast. They can be used in thin-walled or heavy metal sections of castings, but are best suited for placing in the bottom or drag of the mold. Standard perforation is #6 (.075 hole on .125 center). Standard material thickness is .015. For special applications, the size of perforation holes, the perforation pattern, and thickness of material can be modified to meet your specifications.

These chaplets can be produced to resemble a box, Form #1 and 1A, with curvatures, Form #4 and 4A, to resemble a wedge, Form #7 and 7A, or to clip onto cores, Form #8 and 8C.

The information listed in the chart details general characteristics on their dimensional design.

Tubes
tubes

Tubes are manufactured using tin coated sheet steel or non-ferrous sheet, depending on the metal being cast. Primarily they are used to core holes in heavy metal sections, chill metal in castings, or reinforce and ventilate cores.

Due to variety of manufacturing processes and applications the following designs features may be considered. Butt seam, overlapped seam or welded seam, solid material or perforated material, flange(s) on the end(s), indentations, protrusions, and tab(s), wing(s), or ear(s).

Chills
chills

Chills are manufactured using mild steel or wire, generally are tinned or coated with wash, and can be produced in a variety of shapes and sizes. Nails, both horseshoe and straight shank, can also be used as chills. Chills are used to control shrinkage and achieve directional solidification when producing a casting. External Chills are placed in the mold against the wall. Internal Chills are pushed into cores or the mold wall, therefore their mass protrudes into the mold cavity to achieve desired results.

 


Preglued Chaplets
preglued-chaplets

Preglued Chaplets are Motor Chaplets, Triple Head Chaplets, or Double HeadChaplets with a thin uniform layer of glue applied to one head of the chaplet and symmetrically placed on release paper. Because they are ready to be placed in the mold or on a core, increased efficiencies are achieved.

In addition, the uniform layer of glue eliminates variability of glue thickness and reduces excess gas formation. Inventory control is achieved by each sheet having a fixed number of chaplets.

 

Motor Chaplets
motor-chaplets

Motor Chaplets are manufactured from mild steel, generally coated with tin and used in thin-walled casting. Non-Ferrous metals such as aluminum, copper, and stainless steel are available upon request.

The information listed in the chart details general characteristics on their dimensional design. These chaplets can have grooved or plain stems. Perforations pierced in the plates. Extensions or pins riveted or welded which protrude from the plates. The plate(s) can be curved to a specific radius. Additional design modifications can be integrated to meet your specifications.

Height can be produced from 3/16″-4,5 to 3″-76,2.
