Jomar's Model 25 handles higher volumes

Jomar’s newest machine in its injection blow molding (IBM) line is designed to handle large volumes — and comes at a price the company believes is accessible to potential customers. The smallest in the company’s portfolio, it is especially suited for first-time makers of IBM bottles.

The new model replaces the Model 20, which has been discontinued. It made its debut at K 2019.

It is designed to process a wide range of materials and to increase mold cavitation from earlier models without a significant increase in cost. Jomar said it carries an “entry-level” price. The Model 25 has standard screws for IBM grades of PE, PS and PP, plus special screws available for PVC, PP and PET.

Typical applications for the machine include dropper bottles, roll-on deodorant bottles, powder bottles and small jars.

“We’ve found that customers wanted a Jomar, but they either didn’t have the capital required for our larger machines or couldn’t meet their annual volume requirements with our Model 20,” Jomar President Carlos Castro said in a news release. “The need to provide a high-quality, high-volume machine at a lower price point drove the development of the Model 25.”

The first Model 25 has already been sold to a cosmetics company, Jomar said.

The Model 25 has the same footprint as the discontinued Model 20 but features a greater clamp tonnage and casting area, which allows for larger bottles. The Model 25 can mold bottles up to 6 inches in height and 4 inches in diameter.

The unit’s preform clamp has 21 tons of clamping force, and the blow mold clamp has 5 tons of clamping force. The 20-horsepower motor consumes an average of 11 kilowatts (kw) per hour, according to the company.

Casting area is 11.7 square inches by 7.5 square inches.

Shot capacity is 60 grams of HDPE with a 1.125-inch-diameter vertical screw with a 27:1 L:D ratio. Using such a screw, the Model 25 is just 6.75 feet long, 4.3 feet wide and 8.3 feet high. It weighs 3,710 pounds.

Dry cycle time is 2 seconds.

Standard features include a programmable control system with a touch screen that can retain 30 sets of process parameters; two-pressure blow air; alarms for high and low plasticizer temperatures; a preform hot-water manifold; and a blow mold cooling manifold.

The machine has ceramic heater bands and integrated heat controls.

Options include a bottle-orienting stripper system with vacuum, barrel fan cooling, air intensifiers and HEPA filters.

The company said that based on 6,000 hours of annual production, the Model 25 blow molding system can manufacture about 16 million 10-milliliter (ml) eyedropper vials per year.

It also can produce 500-ml pharmaceutical bottles at the rate of 1.2 million per year.
