Single-stage vs Two-stage blow molding

The FMCG market is constantly changing, so businesses must also flexibly adapt to the increasingly shortened product life cycle. Production costs are increasing, so one of the solutions is to cut packaging costs to maximize profits. By understanding that, packaging manufacturers are constantly improving technology to reduce the number and cost of mold production. Therefore, today’s PET bottle production includes two main methods (single-stage blow molding and two-stage blow molding). Enterprises need to choose a suitable one for the product’s [...]

COLD RUNNER SYSTEM STRUCTURE IN INJECTION MOLD MAKING

WHAT IS THE COLD RUNNER SYSTEM The cold runner system is the flow path of molten plastic from the nozzle of the injection molding machine through the sprue bushing, runner, gate, and then into the mold cavity without any heat effect on this plastic flow on the way of the mold. When the mold is cooled, the plastic in the flow path is also cooled, shaped (according to the flow path), and removed simultaneously with the product. Sprues, Runners, and Gates Sprue The [...]

STRUCTURE OF HOT RUNNER SYSTEM

WHAT IS THE HOT RUNNER SYSTEM? “Hot runner” is a system of electrically heated channels used in plastic injection molds. It is used to keep the plastic in the channel always in a molten state to inject directly into the plastic injection mold. Molds arranged with a hot runner channel system are called hot runner molds. The hot runner is mounted directly on the plastic injection mold and is an integral part of the mold. The temperature in the mold [...]

THREE-PLATE MOLD, STRUCTURE AND PRINCIPLE OF OPERATION THREE-PLATE MOLD

The three-plate mold is an injection molding mold that uses a cold runner system. The runners are arranged on two planes. When opening the mold, there is a clearance to take out the runner and the other to remove the finished part separately. So, the three-plate mold structure is larger and more complicated than its two-plate cousin. It is suitable for manufacturing large products or multi-cavity molds requiring multiple nozzles. The three main parts or plates which make up this [...]

EXTRUSION BLOW TECHNOLOGY IN THE PRODUCTION OF PLASTIC BOTTLES

Plastic bottle blowing is the process of creating an empty bottle from plastic materials. This process involves heating and inflating the plastic in the form of a preform or parison. The hollow plastic part between 2 mold plates is similar to the shape of the formed product. Air is then injected to blow the plastic to expand until it touches and fits the mold shape. When the blowing process is complete, the product is cooled, ejected, and the excess [...]

USING PLASTIC MATERIALS IN THE FIELD OF HEALTH

THE ROLE OF PLASTIC IN THE MEDICAL FIELD Plastic has made our lives easier and more convenient. From household appliances, food packaging to medical equipment, plastic has become an indispensable part of life. Plastics can be processed into any shape or size and can be easily functionalized to produce desired chemical or functional properties. Medical instruments that were once made of steel, ceramic, or glass have now largely been replaced by plastics and have proven to be cost-effective and highly durable. Medical [...]

PLASTIC PRODUCTION COST, CHOOSE PLASTIC INJECTION MOLD

I. COSTS IN THE PRODUCTION OF PLASTIC PRODUCTS 1.1. PLASTIC INJECTION MOLD PRODUCTION COST In the production of plastic products, the first cost that needs to be considered is the cost of making the mold. Depending on the complexity of the product to be manufactured, the cost of a mold can range from $1,000 to hundreds of thousands of dollars. The mold with a low number of cavities will save the cost accordingly, but on the contrary, the production cost of [...]
