The Importance of Quality Management in Extrusion Blow Molding

When it comes to the application of blow molding, three things must be in place to ensure quality finished products. First, the machine itself must be cutting edge. Second, the operator must have the proper qualifications for running the machine. Third, quality management must oversee the entire process. Of the three, quality management in extrusion blow molding is the most critical.

Quality management is more than just a person who enforces strict rules. It involves excellent processes, available references, and ongoing quality assessments that make it possible for a manufacturing company to produce parts and components that meet customer demands. In other words, exact extrusion blow molding machine specifications ensure a superior-quality finished product and, ultimately, a happy customer.

To summarize the critical nature of quality management, it provides a structured approach relevant to the plastics making industry using the application of blow molding. As a result, manufacturers can deliver better products, which results in higher customer satisfaction and increased profits.

Stretch Blow Molding and Its Different Applications

Stretch-Blow-Molding.jpg

Stretch blow molding is a manufacturing process that’s well suited for different applications across a broad range of industry sectors.

Blow molding is an engineering procedure in which hollow plastic forms such as water bottles and juice bottles are formed. Stretch blow molding is one type of blow molding that allows the preformed products – in this example that being bottles – to be manufactured into high-quality bottles with high clarity – and the full scope of stretch blow molding allows for an extensive and diverse number of uses. Stretch blow molding is most often used for making plastic bottles for water, juice, carbonated beverages, and a variety of other products such as liquid soaps and detergents.

The primary advantage to stretch blow molding is that it is known for bi-axial stretching (that is, having two axes). There are significant benefits to this process. For example, it makes for improved barrier properties, better clarity of the formed container, improves the malleable strength of the container, and also makes for acceptable impact tolerances. This all means that there’s an increase in the strength of the container along with a reduction in the weight of the container of roughly 10 to 15 percent (as opposed to other production methods). This in turn translates to cost savings while producing high-quality, attractive containers.

What to Look for In a Blow Molding Manufacturer

Blow-Molding-Machine4

Companies that depend on blow molding manufacturing as a component of business will benefit from knowing what qualities to look for in a blow molding machine manufacturer.
Much in the same way that consumers depend on products where the type of container and packaging is important, there are criteria that all companies should seek out when determining the best blow-molding manufacturer and blow-molding processes:
Qualifications and Capabilities: 
This term is used across a significant number of industries. It’s an expression of a company’s operating and production expertise. A manufacturer must be established with industry-proven capabilities that are an assurance to a client’s needs. Qualifications and capabilities is the critical “tell all” of abilities. It’s the “show me” component on which client buying decisions are based. Typically included in this component is a company’s QC – the Quality Control that assures reliability.
State-of-the-art equipment and technical expertise: 
Any manufacturer that offers blow-molding products and services must be fully up-to-date with the most technically advanced blow-molding machines and methods. That equipment and technical expertise will have a direct impact on a company’s products. Your company’s brand, its profits, consumer confidence, and future success will depend on the reliability and excellence of the blow-molding equipment and technical excellence of the blow-molding machinery supplier.
Client product knowledge: 
Imagine buying the product and service from blow molding manufacturers that never took the time to understand anything about your business.

Trouble-Shooting In Plastic Injection Molding Processes And Machinery

Plastic-Injection-Molding

As with any manufacturing procedure, the processes of plastic injection molding can at times require a vigilant analysis and trouble-shooting methodology to ensure efficiency of the operation and end product quality. This article will provide an overview of some of the core components of plastic injection molding processes and machinery and an approach for trouble shooting.

Efficiency throughout every phase of any plastic molding operation is fundamental to Quality Control and Quality Assurance. In order to effectively implement trouble-shooting methods for plastic injection molding machines, it is necessary to understand the full range of the processes, detailed criteria of those processes, the materials, and subsections and specifics of each. Though this is clearly a comprehensive topic, an abbreviated outline is being provided here for space considerations.

Trouble-shooting plastic injection molding processes ultimately comes down to an analysis of four major components: (1) Material; (2) Mold; (3) Molding Cycle; and (4) Machine Performance. Additionally, in the practical world of injection molding, any existing problems tend to narrow down to the following three classifications: (1) Pre-molding; (2) Molding, and; (3) Post-molding. An outline of plastic injection molding machines, materials, and processes – as it applies to trouble shooting – generally consists of the following:

  • Molding procedures (i.e., extrusion blow molding, injection blow molding, etc.)
  • Different machine types and systems
  • Molding and finishing processes
  • Clamp systems
  • Feed systems

How Extrusion Blow Molding Differs From Injection Molding?

If you operate a business that has a requirement for specially formed plastic bottles or containers, such as for juice and water bottles or liquid soaps and shampoos, it’s to your benefit to understand the various manufacturing processes for making those bottles and containers. What follows is an explanation of the extrusion blow molding process and how it differs from injection molding. 

extrusion-blow-molding-process

Extrusion blow molding (EBM) is a manufacturing process whereby plastic is melted and extruded (that is, expelled to form a shape) into a hollow tube; a form or mold. (At this point of the process this material is generally referred to as a “parison,” which is a round melted mass that will then be molded; or formed.) The parison is held and sealed in the metal mold. Air is then blown into the mold thereby shaping it into the desired shape of the bottle or container. Once the plastic has cooled, the mold is opened and the part is discharged. There are two variations of extrusion blow molding: Continuous (with a constant extrusion of the parison) and Intermittent.

Injection molding (AmE or BrE), on the other hand, may seem similar but it is a different process. Injection molding is also a method of manufacturing products and parts by injecting material (such as plastic) into a mold. In this case, plastic in the form of pellets is melted and then injected (forced) into a mold where it cools and solidifies to the shape of the mold. The finished result is the exact copy of the mold.

Blow Molding Purging Procedures

Purging your blow molding machine is necessary to ensure optimal performance and a superior end product. While there are some differences between standard and custom blow molders, the blow molding design is similar enough that there is no real impact on the purging process. Even when it comes to extrusion blow molding vs. injection blow molding, purging is essential.

Blow-Molding

Safety First

If you plan to purge standard or custom blow molders, safety is the number 1 priority. Therefore, be sure that you follow all required safety procedures before the startup and shutdown, regardless of the material. You need to don the appropriate protective clothing, gloves, and eyewear, and use a shield. If the machine has a vented barrel, clean the area around the plug and vent before sealing.

How Does a Blow Molding Machine Work?

Of the many different machines used for manufacturing products, the blow molding machine is one of the most fascinating and useful. Known as extrusion blow molding, the simple explanation as to how this blow mold design works is that air is blown into a parison, shaping the hollow bottle as it inflates. However, there is much more to the plastic extrusion blow molding process.

Blow-Molding-Machine

The Blow Molding Process

The extrusion blow molding process produces plastic bottles of various sizes and shapes. Millions of people use these bottles daily for soda, water, cleaning products, food, and more. With this process, low-pressure air of around 25 to 150 psi is forced into a parison. Multiple materials are used, including Low-Density Polypropylene (LDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Polyethylene Terephthalate (PET), and Polypropylene (PP).

Injection Blow Molding (IBM) Machine: Know Your Part Well Before Sizing Machine and Tooling

The injection blow molding process is a good, reliable choice for producing challenging and delicate parts. Many factors need to be taken into account before purchasing an injection blow molding machine, including technology and price. 

injection blow molding machinery

Prior to selecting the blow molding resin, you also need to know the part’s specifications, the final weight, and the shot size. Typical IBM resins are HDPE, LDPE, PP, Nylon, etc.

Cycle time and shot size affect the IBM machine’s output. To conservatively predict the IBM machine’s maximum output, assume 90 percent of its highest screw speed. The extruder should have a low melt temperature, as heat increases during the cycle time.
