What are the advantages of the development of commodity molds?
Advantage 1: The molding time of commodity molds is shortened
Because there is no limit to the cooling time of the runner system, the parts can be ejected in time after they are solidified. Many thin-walled molds produced with warm runner molds can have a molding cycle of less than 5 seconds.
Advantage 2: Save the production cost of daily necessities molds
Because there is no cold runner in the pure warm runner mold, there is no production cost. This is especially important for the use of expensive plastic items.
In fact, the major international manufacturers of warm runners have developed rapidly in the era when petroleum and plastic raw materials are expensive in the world. Because this technology has played a great role in many fields, not only in This is the commodity mold.
Advantage 3: Greatly simplify the production follow-up process of daily necessities molds
The parts are formed after the warm runner mold is formed. There is no need to trim gates and recycle cold runners, which is beneficial to production automation. Many foreign manufacturers have combined warm runners with automation to greatly improve production efficiency.
At present, daily necessities molds have been widely used in the industrial field, and the market demand is huge. With the development of new technologies, the creation of multi-color co-injection and multi-material co-injection technology, the development of daily necessities molds is worth our expectation.
Plastic mold is an abbreviation for a combined mold used for compression molding, extrusion molding, injection, blow molding and low foam molding. The coordinated changes of mold convex and concave molds and auxiliary molding system can process a series of plastic parts with different shapes and different sizes.
It mainly includes a female mold with a variable cavity composed of a female mold combined substrate, a female maold component, and a female mold combined card plate, and a convex mold combined substrate, a male mold component, a male mold composite card, a cavity cutting component and A punch with a variable core composed of side-cut composite plates.
In order to improve the performance of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., must be added to the polymer to become plastics with good performance.
