View Full Version : Babyplast Alternatives for micro molding?

I am aware of the following mini machines:

Babyplast 610 - max 0.5 oz shot size, no water used
Boy xxs/xs - max 0.33 oz shot size
Nissei 7 ton (out of production)
Sumitomo 7 ton, max 0.2 oz shot size

I know Battenfield and Sodic make expensive micromachines. Who else is out there comparable to Babyplast for production grade machines, preferably 0.5 oz shot size or higher?

Relating one such case to PlasticsToday at the recent Interplas show in Bangkok, Thailand, Lily Lee, Business Development Manager at Formative Tech noted that the 6-tonne Babyplast 6/10p micromolding press consumed just one-sixteenth of the energy used by a 50-tonne all-electric press. Further, the 6/10p molded the 0.053-g PBT parts in a 32-cavity tool versus 16-cavity for the 50-tonne all-electric in a cycle time of 12 seconds versus 15 seconds. "While the runner weight is higher for the micro-molder, we were able to save $3,290 on a run of 500,000 parts," notes Lee. "The 500,000 parts were produced in just over 50 hours versus just over 130 hours for the 50-tonne all-electric," she adds. "The reject rate is only around 0.4%, which is much less than you'd expect for a standard machine molding very small parts.

There was a company out of Chigago that came up with a very inexpensive unit. I saw their article in Plastics News. I did a quick search and did not find it. I would suggest you try to google it. It was also electric I believe. It is not one of the known big brands.

Suhas,
Thanks for your help. Was it this machine?

Does it look production grade to you? My volumes are ~100k/ea but I have 10 different parts. If it can handle abuse I can buy 4 of them for the price of one babyplast. It seems a bit slow on youtube:

I hope you found what you needed already. Yes APSX-PIM can make 100K parts a year easily. Typical cycle time is 60 secs or less depending on the parts size and the plastic type.
