Industrial Blow Molding

Industrial Blow Molding

As an industry leader in blow molding, Blow Molded Products pays the utmost attention to quality and detail from start to finish. We specialize in industrial blow molding as well as custom designed products.

In the earlier days of industrial blow molding, there were quite a few obstacles to overcome. Material and color changeover times often spread from 8 hour to several days depending on the color and the material required for the project. Poorly designed heads often led to machine downtime, and bi-annual maintenance and repairs led to weeks of downtime. Many periods of downtime were due to waiting for service technicians to help service the machines.

Basic manuals, schematics, and sequences of operations were often outdated and did not pertain to newer machines that were put in place, as the older machines were semi-automatic, relying on an operator that led to an unpredictable control of cycle times. Mold replacement and changes took a minimum of a full day or two that often included changing head tooling.

Set up changes from product to product were common, leading to issues due to having to adjust the machines frequently. Cycle times also varied due to the parison drop time, press closing time, blow time, exhaust time, decompression time, clamp opening, gate opening, manual part removal, gate closing and clamp moving to pre-close positions.

The current industrial blow molding processes that Blow Molded Products employs is much more efficient in terms of costs and time. Our current head technologies allow for color changes in as little as 20 minutes to about one and a half hours for the most difficult changeovers. Our heads also require less maintenance, and run more efficiently. A properly designed head eliminates any potential galling from metal to metal rubbing on the moving internal sections of the flow paths of plastic materials. Our modern heads allow for rapid disassembly, cleaning, and reassembly to change colors or materials within an hour.

Blow Molded Products also takes the required time to properly set up our equipment, ensuring that it runs as efficiently as possible to produce the highest quality products. Our state-of-the-art machines are tuned to run automatically to give a more consistent cycle time. In addition, our innovative molds feature quick change connections for water, air, and hydraulic components. The processors used in our facility are able to make complete mold change overs in a fraction of the time.

Customer specifications are one of our highest priorities, and why we custom tune and tailor our setup per your needs. Our engineers utilize industry-standard, computer assisted design programs (CAD) for product manufacturing, mold and fixture designs.

Since our 3-shift mold making capabilities allow our projects to proceed with the shortest lead times and maximum efficiency, we are able to extend the savings to you. We offer custom designed industrial blow molding equipment to meet your specific needs, featuring custom accumulator head blow molding systems with closed loop hydraulic and electronic controls. We also work with industry leading screw designs to process polyolefins and engineered thermoplastics. Blow Molded Products leverages OEM quality control upgrades, ANSI safety compliance, head reconditioning, clamp rebuilds, and replacement screws and barrels in order to run as efficiently as possible. We are proud to do numerous online and offline, secondary and assembly operations as part of our commitment to you; ensuring that your final product will be ready to go before it leaves our site.

No job is too big or too small for Blow Molded Products. We have a history of manufacturing and making parts that other companies will not even attempt. Contact us today to learn more!
