production. The BA 25 system has also excellent plastification. BEKUM extruders use a special screw geometry for optimum homogenisation of the material. An energy-saving AC motor ensures that the material is melted gently at low rotational speeds. The patented spiral mandrel distributor head technolo- gy from BEKUM allows uniform wall thickness over 360° of the water bottle and offers reproducible product quality that is se- cond to none. This in-house development by BEKUM practical- ly excludes article thinning and flow marks, ensures a crystal- clear water bottle transparency with a cloud-free surface and, by doing so, enables products of high quality. High efficiency at the forefront The highly transparent PC containers are blown out in a special blow mould, which has multi-zone temperature control and magnetic quick-change inserts, with or without a handle. The BEKUM single-station blowers of the BA series achieve an un- disputed output of over 160 containers / hour at a net weight of 750 g based on the reference article “Nestlé 5 Gallon Aqua Design without handle”. This high output rate is possible without compromising the high article stability as well as the crystal-clear transparency, even at demoulding temperatures of over 85°C. Sophisticated polycarbonate PC containers are country-specific and made out of pure new materials (e.g. from Bayer Makrolon, Mitsubishi Novarex and other PC materials), a varying material mix of new material and recycled material, as well as 100% recyclates. Processors know: When melting, polycarbonate is a sensitive material. This re- quires specially tailored material handling systems for material drying and material inlet. After shaping, the cooled article ma- terial and flash are very hard, requiring coordinated cutting mills. For an optimally coordinated, high-performance periphe- ry, BEKUM brings with it the experience gained from many installed user projects and relies on tried and tested, high- performance partners. Practice-oriented automation to increase productivity Last but not least, automation plays an important role for the user if efficiency should be increased. Especially for containers with an integrated handle, fully automatic and guided flash re- moval is important. Furthermore, the automated removal with removal grippers and alignment by a turning station for placing on an article production line, increases efficiency of the opera- tion. With its convincing performance characteristics and the system design optimally aligned to PC water bottle production, the BA series is a reference in water bottle production.
