They are then cut and blown into a mold to form a bottle. Shuttle machines are typically used for shorter run lengths or bottles where the neck geometry requires a more
How to Solve Blow Molding Problems -
blown bottles. One cause is an imperfect parison. Other causes are related to the mold and the blow molding process. 1. Poor mold surface n Refinish a poor or worn mold surface.
The Realities of Aluminum Tooling | MoldMaking
The Realities of Aluminum Tooling. Using aluminum tooling instead of traditional tools steels reduces cycle time and costs, but requires up-front, open
Let’s Be Clear About Aluminum | MoldMaking
Following are some general facts about aluminum tooling: • Aluminum alloys have a Brinell hardness range of 150 to 180, and a Rockwell hardness range of B82 to
Stretch Forming 101 |
An Introduction. Stretch forming is a metal forming process that simultaneously stretches and bends a selected material over a machined form, called a die, to form a part with one
Texturing Methods for Injection Mold Cavity
The etching is usually performed using the flow or dunk method. The flow method involves allowing the etchant solution to run across and off the mold cavity
How To Open The Aluminum Plate Stretch Bottle
When the clamping unit separates the mold halves, the ejector bar actuates the ejection system. The ejector bar pushes the ejector plate forward inside the ejector box, which in
Aluminum Mold Plate (5083 Alloy) | Midwest Steel

Internally low levels of porosity are guaranteed by our casting supplier. Easy to recycle, it has a higher residual value at the end of its useful
M-1 Aluminum | Aluminum Mold Plate Suppliers | Howard Precision Metals
M-1 can be used for a variety of applications: Injection Molding – M-1 aluminum is used for mold applications where 1 to 12 cavities are required. M-1 has a faster cool-down rate, therefore increasing productivity and reducing overall costs. Blow Molding – M-1 can be used for blow molding because of its high Brinell
Stretch Forming 101 |
An Introduction. Stretch forming is a metal forming process that simultaneously stretches and bends a selected material over a machined form, called a die, to form a part with one or several different curve radii. This process produces perfectly curved parts with smooth, wrinkle-free contours. The aerospace industry initially invented the

Sheet Metal Forming -
In each step, a punch forces the part into a different die, stretching the part to a greater depth each time. After a part is compley drawn, the punch and blank holder can be raised and the part removed from the die. The portion of the sheet metal that was clamped under the blank holder may form a flange around the part that can be trimmed
Eliminate Problems with Container Handles | Plastics
In a typical handleware container (Fig. 1), the aspect ratio of the handle is the ratio of the major axis (width of the handle perpendicular to the parting line) to the minor axis (width of the handle parallel to the parting line). An aspect ratio of 1:1 is optimum; at most, a 2:1 ratio can be blown. Higher aspect ratios are certain to create
TOOLING: Flash-Free Molding: Part Two | Plastics
Feather flash is little strings of plastic along the edge of a part on the main parting line. The root cause of this is lack of clamp force and the clamp blowing open under injection pressure, allowing the plastic to flow between the shut-offs, causing the little strings of plastic. On the tooling side, I have seen many times where shut-off

Glass Bottle Slumping Tutorial –
Glass bottles need to be placed on a surface that has been kiln washed or shelf paper such as thin-fire paper can be used. This is to prevent the glass from fusing to the shelf. When using kiln wash, be sure the surface is very smooth. Any brush strokes, bumps, etc. will show up in the glass. Even seams between sheets of thin-fire paper will
