Hydraulic Clamp Unit Allows Low Cost Tooling and Quick Changes
Babyplast micro-molding machines
The Babyplast hydraulic system offers many advantages over toggle-type mechanisms:
- Sensitive low-pressure mold protection
- Platens and tie bars act as the mold bolster, providing alignment of mold halves without the need for locating pins, allowing more space for the cavity.
- Platens and tie bar design also enables quick tooling changes — like replaceable cavities in a conventional mold.
- Individually controlled cooling circuit is built-in to the fixed platen.
- Additional cooling circuits are provided to feed both halves of the tool.
Processing Features for Special Applications
Babyplast micro-molding machines
Babyplast's unique injection unit improves accuracy and reduces costs. Babyplast machines feature a specially-designed plasticizing chamber which feeds a micro-plunger for very accurate injection. This eliminates inconsistencies caused by conventional check ring designs. It also reduces material residence time and the risk of degradation.
- Five different standard plunger diameters
- Offset injection feature reduces molded-in stress and material wastage — and can create enhanced cosmetic finishes.
- Auto-purge for simple start-up and shut-down.
- Micro pellets are not required.
- Ideal for all engineering materials such as glass-filled and high temperature polymers.
Simple yet precise control
Babyplast micro-molding machines
The Babyplast is controlled by two powerful microprocessors that monitor movements, times and temperatures, with user interface via a clearly laid-out graphical terminal.
- Quick, simple and accurate machine set-up — even with material shot sizes in the sub-gram range.
- Fully automatic, unattended machine cycling
- Auto start-up feature allows the machine (and hot runner, if used) to be turned on at a preset time to be ready at the start of shifts.
- Offset injection function
- Memory up to 100 tool settings.
- Key parameters are password-protected and automatically date-coded for added security
- Quality control package closely monitors for out-of-tolerance parameters.
- Proportional hydraulics for improved control and accuracy.
- Quiet in use — only 68dB
Solutions for a Wide Range of Materials and Markets
Babyplast micro-molding machines
- Babyplast is ideal for producing parts that weigh from 0.01 grams to a maximum of 15 grams.
- Babyplast has no equal in the field of micro injection molding with over 7,000 applications using a wide variety of mold types and thermoplastic materials.
- The majority of the molds developed for Babyplast are not for preliminary production or prototypes, but for full production.
- The materials used range from PP - PS - PE - ABS - PA to PC - POM - PBT - PPS - PPO - LCP, from thermo rubbers to filled materials.
- Molds have been developed with up to four slides, single and multi tips with up to four tips, and as many as 40 cavities in one single mold.
- Babyplast is primarily used in technical fields: electronics, automotive, micro-mechanics, medical, and furniture, but it is also used by manufacturers of toys, promotional products, cosmetics and costume jewelry.
