Laundry Basket Size: 489.2 X 622.7 X 233.9mm Basket Weight: 0.59 kgs Gate system: 5 tips Hot Runner Not all molding applications are suitable for runner-less molding. Some materials are heat sensitive and the time to temperature relationship - especially when the shot size is very small - can be a problem. Some families of parts, for handling and orientation purposes, may be best kept attached to the runner until they reach another downstream operation. In other instances, the required volume of parts may be so small that the added cost of the hot runner system to the mold price cannot be justified.
Each cavity of this cap mold is designed with separate inserts, so that each cavity product in the process of injection molding maintain the same injection molding pressure, clamping force and other molding conditions, so that the product quality is more stable and reliable. Moreover, the independent insert design can make the life of the mold longer. If there is any problem with the parts, the parts can be directly replaced without affecting the production schedule.
This double color oil cap is applied for automobile lubricants, which is made by double color rotary injection molding process. The mold is composed by two different molds, one for making first color with customer's logo, the second mold is for making outer color. This kind of double color injection is better then single color or screen printing, meanwhile, the logo is not easy to be faked which is the best solution to rise company image up.
Generally speaking, the ejection action of the finished product from the mold is completed at one time, whether using single or multi-component ejection mechanism. However, due to the special shape of the finished product, or the requirement of mass production, if the finished product is still in the mold cavity after one ejection, or when it can not automatically fall off, it needs to add another ejection action. Such ejection action design is called 2 Times ejection. 2 Times ejection can make ejection flow smoothly. For some products requiring larger ejection travel, the use of 2 Times ejection can reduce the force exerted by the ejection pin and avoid the defects caused by the ejection pin.
Due to suddenly power failure, mold can not be opened while machine is under high pressure clamping. It is headache for this unexpected trouble.
Thread design sometimes exists in products for assembly purposes. It can be directly formed or machined after forming. For threads that are often disassembled or under heavy loads, the following principles should be taken into account when designing threaded inserts:
There are two ways to make two-color products, one is over moulding by 2-step injection, the other is double injection by single step, which includes using rotary table or axis to make two-color plastic injection products.
