Tahara to exhibit at K 2025
At the upcoming K 2025 show in Düsseldorf (Oct. 8-15), Tahara Machinery Ltd. of Japan, a subsidiary of the Japan Steel Works (JSW), will introduce its MBD series: all-electric double station extrusion blow molding machines with internet connectivity. The range of product sizes for these machines is 300ml to 1.5 liters. The MBD-C33A/54E2Z-AP(C3) at the show will mold three-layer, 1L bottles, using Tahara’s own coex die head. The middle layer is composed of post-consumer recycled (PCR) resin.
This 3-layer, 3-head model was awarded an Environmental Award at Plastpol 2024.

Multilayer Molding with PCR
Notably, the machine on display can mold bottles with eco-friendly materials such as PCR, polyethylene containing calcium carbonate, and bio-based resins in the middle layer. Its screw design, featuring barrier flights, a Maddock mixer, and dam flights, ensures excellent mixing and uniform dispersion of PCR materials.
Since launching the world’s first all-electric blow molding machine in 1994, Tahara has built a strong track record of meeting diverse customer requirements, offering screw designs optimized for specific materials.
The 1L bottles molded at the show will have a three-layer structure:
| Layer | Inner | Middle | Outer |
| Resin | HDPE | PCR | HDPE + Masterbatch |
| Ratio | 20% | 60% | 20% |
Using PCR in the middle layer helps bottle molders comply with increasingly strict environmental regulations while reducing material costs. Regrind material can also be used in the middle layer, enabling waste resin reuse. Additionally, adding pigment only to the outer layer helps lower raw material costs.
Why Multilayer Matters
Though recycled materials can potentially affect appearance or raise concerns about contents contacting them, multilayer bottles solve these issues. Virgin resin on the inner and outer layers prevents contact between the contents and recycled or regrind layers. This avoids chemical reactions and protecting the appearance of the bottle.
At the exhibition, Tahara will also showcase co-extruded bottles used for food, cosmetic, and agrochemical containers. Six-layer food containers provide excellent oxygen barrier properties. Meanwhile, pesticide containers use PA resin for strong chemical resistance. Tahara’s original coex head extrudes multilayer structures with uniform thickness in each layer, ensuring no layer disruption. Detailed layer structure materials are available on request.
Remote Maintenance with EWON
Furthermore, the machine is equipped with “EWON” for remote maintenance via VPN. By allowing our operators to perform initial diagnosis using the customer’s machine information (logging data) and PLC data (programs and error history), the need for on-site inspections can be reduced. This enables faster on-site support by preparing necessary parts and tools in advance. In some cases, issues can be resolved entirely through remote support, cutting down both the time and cost of dispatching engineers. Moreover, accurately identifying faulty parts helps avoid unnecessary replacements.
