Packaging and pharmaceutical machinery, built to order for drug manufacturers
IWAKURO Mfg. Co., Ltd. develops and builds automatic packaging lines and pharmaceutical processing machines. Each machine is designed to the customer’s requirements, and design, parts machining, assembly, adjustment and after-sales service are all carried out at our own factory in Toyama, Japan.
AboutMachines for medicines since 1948
We began with pill making machines, moved on to strip packaging machines, and then to PTP (blister) packaging machines, developing machinery that automates packaging as the pharmaceutical industry adopted GMP and factory automation. Today we work with about 200 pharmaceutical manufacturers in Japan*, and have delivered machines to China, Mexico and Ireland.
* Number of customers according to our own records.
ProductsProduct line-up
Our main products are listed below. Specifications are decided machine by machine, so please ask about machines not shown here. Each item links to its product page (in Japanese).
-
872
PTP (blister) packaging line (No. 872)
Forms the blister film in-line, fills tablets or capsules, seals the lidding, then perforates, embosses and punches out the sheets. IWAKURO’s original continuous flat-plate forming keeps a constant forming pitch for stable running. Up to 8,000 tablets/min; film width up to 300 mm.
-
888
Four-side-seal sachet packaging line (No. 888)
For granules and fine granules, at up to 800 sachets/min. Our film control keeps the empty-sachet weight consistent, and the fill weight is measured and corrected automatically during packaging.
-
889
SP (strip) packaging line (No. 889)
Multi-lane strip packaging of tablets in heat-sealable film. Every sheet is weighed, and sheets outside the weight range are rejected automatically.
-
887
Stick packaging line (No. 887)
Packs granules and fine granules into stick packs. The fill weight is measured in-line and fed back automatically.
-
724
Tablet counting and filling machine (No. 724)
Counts tablets with servo-driven rotors and fills them into bottles. Missing-tablet and rotor-jam detection on every lane prevents miscounts.
-
370
Pill making machine (No. 370)
Forms kneaded material into round pills. The main axes are individually servo-driven and the settings are managed numerically. This is the machine IWAKURO started with in 1948.
StrengthsWhy manufacturers choose IWAKURO
- One factory
From design to installation, under one roof
The people who design the machine, machine its parts, assemble it and adjust it all work in the same factory. Main parts are made on our own machine tools, which gives both high precision and short lead times.
- Numerical control
Run by numbers, reproduced by numbers
We develop the machines and their control software ourselves. Conditions such as temperature and pressure are managed as numerical values, and selecting a product switches the machine to its validated sealing conditions (patented).
- After-sales service
Supported by the people who built it
Replacement parts are machined in our own factory, which shortens lead times. Inspection and repair, overhaul, replacement of discontinued electrical parts, modification for new products and operator training are handled by the engineers who designed and built the machine.
What we provide with each project
- Packaging tests with the customer’s product and packaging material before an order
- Factory acceptance tests (FAT) at our factory before shipment
- Installation and adjustment at the customer’s site, with operator instruction
- Support in preparing IQ/OQ qualification documents
- Line engineering through to pillow packaging and cartoning, by our group company Iwakuro Co., Ltd.
