Here Is Everything You Need to Know About Blow Molding

What Is It?The HistoryWhat Can You Make?The ProcessBlow Molding MaterialsAdvantagesYour Product’S About to Blow Up!This process can be used to manufacture plastic products. The process involves heating a plastic tube (known as a preform or parison) to its melting point and then putting that into the cavity of a mold. They then use compressed air to inflate the molten plastic like a balloon so that it takes the shape of the mold but is hollow inside. The amount of plastic used and the air pressure determines how thick the final product is. See full list on maycointernational.com Blow molding has its roots in glass blowing, where a craftsman would heat the glass to its melting point and then blow through a tube to inflate the glass. This process has been around since as far back as the 1800s. A patent from the time shows the process being used with celluloid polymer. These early methods were not suited for mass production. In the 1930s, they developed commercial machines to manufacture blow-molded bottles and made mass production possible. The materials available were too brittle and took too long to produce to effectively utilize the process to make large quantities. Blow molding exploded into industrial prevalence with the creation of low and high-density polyethylene. This revolutionized many industries including the soft drink bottling industry and the automotive industry. See full list on maycointernational.com You can make just about any hollow plastic container with blow molding, but the process isn’t limited solely to bottles. Here are some commonly blow-molded products: 1. Construction Barrels and Barriers 2. Stadium Seating 3. Coolers 4. Fan Housing 5. Toys and Sporting Goods 6. Watering Cans Blow molding is also widely used in the automotive industry and makes the design and mass production of auto partssimple and cost-effective. Here are some commonly blow-molded automotive parts: 1. Automotive Ductwork 2. Liquid Reservoirs 3. Mud Guards 4. Consoles 5. Seating 6. Storage Systems 7. Electrical Covers 8. Fenders 9. Paneling To sum up, blow molding has a wide variety of uses and is a great way to produce a large number of parts inexpensively. See full list on maycointernational.com There are a few different types of blow molding. Their differences lie mostly in how they form the parison, the size of the parison, and how the parison moves between the molds. The main types of blow molding are: 1. Extrusion Blow Molding (EBM) 2. Injection Blow Systems (IBS) 3. Injection Stretch Blow Molding (ISBM) Modern blow molding is a largely automated process, allowing for the production of thousands of parts in a short time period. The process includes the following steps: 1. Plastic pellets are fed into the machine via a hopper or screw depending on the machine. 2. Plastic melts and then gets shaped into a parison, which looks like a tube with a hole at one end. 3. Clamped in place inside the mold. 4. Compressed air inflates the parison. 5. The heated plastic balloons to fill the space of the mold. 6. After the plastic cools, the machine opens the mold and removes the part, sending it on to any applicable finishing, if any. Furthermore, with IBS and ISBM, a preform replace... See full list on maycointernational.com Plastics that are suited for this process include: 1. PVC 2. PET 3. Nylon 4. ABS 5. EVA 6. TPE 7. Low and High-Density Polyethylene 8. Polypropylene 9. Co-polyester 10. COP and COC 11. Polystyrene The wide variety of materials available for use in blow molding means that you can use the process to develop parts to fit your exact needs. See full list on maycointernational.com There are many advantages to the blow molding process over other forms of plastic product manufacturing. Blow molding is a cost-effective alternative to injection molding, with both production and machinery being cheaper typically. Blow molding works well for products that are one single piece. It can produce objects that do not require assembly or the connecting of halves. Therefore, particularly effective for containers that require exterior threading. Blow molding also reduces flash. Flash is the little burs or plastic bleed around seems of products. This excess plastic from the production process requires extra finishing work to sand off or remove it before a part can be shipped. Blow molding techniques create a little-to-no flash, resulting in quicker turn around times for blow-molded products.

Blow Molding Design Guide – Custom-Pak, Inc.

A. Blow Molding ProcessB. MaterialsC. Capturing The ParisonD. Exterior Surface (Mold Cavity) DesignE. Interior Surface (Mold Core) – DesignF. Air SpaceG. Creating StructureH. FinishingThe first step involves mixing, melting and pushing plastic (extrusion) to form it into a tube called a parison that will be used to make the part.A mold is used to make the part shape you desire. The mold has two halves that are closed around the molten parison.Air is blown into the inside of the parison to expand the molten plastic against the mold surface.The mold is cooled to set the plastic to the new shape of the mold.See full list on custom-pak.com Material selection is a critical aspect of design and should involve serious study of: 1. the plastic resin properties 2. the material cost 3. the processing properties 4. your finished-part objectives Although there are thousands of plastic materials available, most won’t meet the needs of your product. Experience with blow molding grade materialsis essential and we have practical molding experience using every blow moldable material See full list on custom-pak.com In order to design a blow molded product, you must understand the interaction between the molten plastic parison and the mold. If you’ve blown a bubble from bubble gum you can understand blow molding. The plastic material stretches like the gum and if it gets too thin it ruptures. Since the parison is extruded as a tube, it is easy to make a tube or bottle shaped part, not much stretching occurs. The two mold halves open, the parison is inserted,the mold halves close and the part is blown. The split between mold halves is known as the parting line. There is often a knife like edge on the parting line around the part shape known as pinch-off. If the part shape to be molded is changed from a tube into a flat panel type part, the parison tube must be flattened to make the panel. When this happens the circumference of the parison becomes the surface that needs to cover the width of the panel. So we try to have a large enough parison diameter that as it flattens, it can be captured by th... See full list on custom-pak.com The inner and outer walls of the part are formed simultaneously and integrally, but interior and exterior designs are essentially independent so we review them separately. As the design develops, the designer should begin thinking about the interaction of the plastic and the mold that will produce the part. The visual exterior of many products is formed in one half of the mold called a cavity. Following are some of the features of mold cavities the designer will want to consider. See full list on custom-pak.com The interior surface of double-wall blow molded parts is normally formed by a mold core. Since the mold core must fit inside the cavity, there should be no question it meets the same W>2D overall size requirement as the cavity. The half of the parison that is draping over the mold core is already beginning to set as the air is injected into the parison. As in the cavity, the plastic begins to stretch to fit the mold contour. Almost no flow occurs. Unlike the cavity, some different rules apply. See full list on custom-pak.com It is the combination of closing the mold on the parison and the expansion of air inside the parison that forms the part. The designer must leave sufficient space between the inner and outer part surfaces to permit adequate blowing of air into every square inch of the part. If the air passage inside the part is reduced or obstructed, the part will not form. See full list on custom-pak.com The double walls in blow molded parts provide engineers with a tremendous opportunity to create structure within the plastic part. A properly designed double-wall part will be substantially stronger than a ribbed single-wall part of equal weight and can easily outperform metals in many applications. There are several ways to add strength to blow molded part designs. See full list on custom-pak.com There are a limitless number of secondary operations that can be performed on a blow molded part to meet the needs of the finished product. Drilling, sawing, milling, cnc routing, die cutting, punching, riveting, screwing, sonic, spin or heat welding, and surface treating are common operations. Nearly any secondary step can be performed economically if the right equipment is available. A surprising number of operations can be done in-mold. Custom-Pak provides a huge variety of secondary operations equipment at no charge. Decorating molded parts requires planning in the design stage. For heat transfer or hot stamp decorating, the part design must provide a means to support the tonnage of the stamping process. For in-mold labels, magazines to hold the labels and mold surface locators must be prepared. For embossed plaques, the attachment method should be included in the part design. Texture is commonly applied to mold surfaces. Blow molding textures are typically etched .008” to .012”... See full list on custom-pak.com

How Much Does Injection Molding Cost? | Rex Plastics Mold ...

Mold balancing plays an important role in injection molding, because of that we would recommend a 24 cavity mold. The parts are divisible in pairs with that amount and will run much better. The ballpark estimate for a cold runner mold that size would be $15-$20,000, and the part price would be under $.09 each for 20,000 parts ordered.
