![]() While it isn’t impossible to extrusion blow mold PET, it is less common, as the resin requires extensive drying. PET is a polyester that is usually injection blow molded into clear containers. Special processing equipment is recommended to prevent corrosion from HCl. ![]() Common applications include soft medical parts, bellows, and traffic cones. PVC is translucent and comes in rigid and soft forms - the soft resin is typically used in blow molding. Some clarified versions provide “contact clarity.” PP recycling is common under code 5.Īlthough PVC is the world’s #3 plastic, it has been heavily scrutinized for using cadmium and lead as stabilizers, releasing hydrochloric (HCl) acids during processing, and releasing residual vinyl chloride monomers after molding (most of these problems have been reduced). It’s molder-friendly as well as translucent and easily colored. PP is commonly used in elevated temperature applications, such as dishwasher tubes and medical parts that require autoclave sterilization. PP is similar to HDPE, but slightly stiffer and lower density, which provides some advantages. PP is the world’s #2 plastic - it’s an extremely popular injection molding resin. It is also molder-friendly, translucent and easily colored, chemically inert, and commonly recycled under code 4. The highest usage is blown film for plastic bags. Common applications include squeeze bottles, traffic channelizers, and boat fenders. Generally, the higher the ethyl-vinyl-acetate (EVA) content, the softer the molded part. LDPE is used for softer products that require a high level of stress crack resistance or flexibility. Variations of LDPE include linear-low (LLDPE) and combinations with ethyl-vinyl-acetate (LDPE-EVA). PE the most commonly recycled resin with recycling code designation 2. It’s molder-friendly, translucent and easily colored, and chemically inert (FDA approved and perhaps the safest of all plastics). It’s used in a vast array of products, including bottles for consumer liquids such as shampoo and motor oil, coolers, play structures, fuel tanks, industrial drums, and carrying cases. HDPE is the world’s #1 plastic and the most commonly blow molded plastic material. Here’s an introduction to the characteristics, benefits, and drawbacks to resins commonly used in blow molding. Cost, density, flexibility, strength, and more all factor into what resin is best for your part. ![]() ![]() The electrical control system can be equipped with different brands first.Choosing the right plastic resin for your blow molding project can be a challenge. According to the customer's output and product requirements, configure single-die and multi-die (up to 6), composite layer single to 6 layers.ģ. The product names are respectively : Plastic bottles, barrels, cans, tool boxes, car shaped hollow parts, automobile fuel tanks, hollow seats, trays, chemical packaging barrels, hollow bed boards, desktop boards, etc.ġ.H series is a new structure, using double linear guides and other technologies.Ģ. The products are used in chemical, pharmaceutical, food, cosmetics, automobile, decoration and other industries. It is suitable for the production of hollow products such as PP/PE/PS/ABS/PC plastics as raw materials and volume from 5ML to 1000L. The company incorporates the latest technologies of plastic machinery manufacturers in Europe and the United States, combines its own design solutions, and designs a series of extrusion blow molding machines for customers with different specifications to meet different requirements.
