Mattel Vac-U-Form Machine Rebuild Kit with Stainless Platform and Aluminum Oven Cover

This rebuild kit brings a vintage Mattel Vac-U-Form machine back to life and makes it work better than it did out of the box. It replaces the parts that wear out or go missing on these 40 plus year old machines and fixes the weak vacuum that keeps most of them from forming clean, sharp parts.

Poor vacuum on a Vac-U-Form comes from three things: a failing flapper valve, a dry and dirty cylinder bore, or a leak where the cylinder bore meets the upper platform. This kit addresses all three. If you can push the vacuum handle down while covering the vacuum hole with your finger, or you feel a puff of air from the hole on the up stroke, your machine needs it. On a machine that is already working normally, the kit can still add up to 3 inches of mercury of vacuum.

What's in the kit

• Aluminum oven cover with an insulated knob. It sits over the heater while the plastic warms, cuts heating time by up to 10 times and lets you form thicker sheet, up to 30 mil. Knob style may vary.
• Stainless steel vacuum platform in 18 gauge 304 stainless. The original plastic platform was easy to lose or break, and it had fewer than 100 holes. This one has 74 holes per square inch, over 600 in all, for a tighter seal around your tooling.
• Medical grade silicone flapper valve to replace the original rubber flapper, plus fast set silicone sealant to seal the cylinder bore to the platform.
• High speed drill bit for opening the vacuum hole to fit the larger valve.

Installation requires drilling out the existing vacuum hole to fit the oversized valve. The drill bit is included, and the rest of the job takes basic hand tools and an afternoon.
