Product Description Specifications For products with different outer and inner-layer material, traditional two-step insert molding becomes one-step.

FB-C Series Sandwich / Interval Injection Molding Machine FB-110C~180C   Sandwich injection molding is one of the newly developed injection molding methods. To accomplish such a molding method, an additional barrel is added to a traditional Plastic Injection Molding Machine to form an independent double barrel with specially designed nozzle. During the injection process, this double barrel can concurrently inject two types of molten plastic, via the same nozzle, into the mold to achieve double material simultaneous injection. The outer layer of the mixed molten plastic is called the skin material, while the inner layer is called the core material.   Advantages  1.For products with different outer and inner-layer material, traditional two-step insert molding becomes one-step. 2.The different color combinations give old products (molds) new life. 3.Low viscous materials can be used as core materials to reduce injection pressure. 4.Recycled and low-quality materials can be used as core materials to increase product utility.
5.High-quality materials with anti-magnetic interference properties and high surface quality can be used as skin materials to increase product utility.
6.Appropriate core and skin material combinations can reduce the residual stress and increase product hardness. 7.Sandwich injection Molding Machine are able to produced single color which provides a multifunction and flexible molding method. This increases the processor's capability to produce high-quality and low-cost products.
Under the pressures of a highly competitive market, how to produce high value-added products while keeping the costs down has become a critical issue for plastic processors. After years of hard work and research, FCS has successfully pioneered the making of the sandwich injection molding machine to assist processors in upgrading and switching their machinery.   Other  features 1. There are two sets of proportional control valves which can simultaneously control the pressure and speed of both sets. 2. With an accuracy reaching 0.01mm, linear potentiometers are used in the two injection sets and clamping molds to accurately control the injection process and the opening and closing of mold. 3. With features such as limitations for screw cold starts, broken wire detection, etc., a PID temperature controller is used to control the temperature at ±1°C.  4. The microprocessor control system not only has memory functions, it can also perform 4-stage injection, 3-stage hold pressure, and 3-stage back pressure.
