Abstract:

Recently, rapid heat cycle molding technology has been developed based on the mold heating before each polymer injection stage. For this process, successful heating and cooling phases are of great importance to ensure the cycle productivity and product quality. In this study, a three-dimensional model was developed to investigate the thermal response during the rapid heat cycle molding process. The procedure uses the finite volume method and the fractional area volume obstacle representation to obtain the thermal behavior of both polymer and mold until reaching the regular cyclic regime.

Abstract:

The rapid thermal cycle molding (RHCM) belongs to the injection mold temperature control system which is helpful to improve mold ability and enhance part quality. Despite many available literatures, RHCM does not represent a well-developed area of practice. The challenge is the uneven distribution of temperature in the cavity after heating, which mostly leads to defects on the surface of the products. In order to obtain uniform cavity surface temperature distribution of RHCM, the power of heating rods of the electric-heating system in an injection mold was optimized by the response surface met

A fully transient method for the simulation of the coupled plastic part and mold temperature in the filling stage of Rapid Heat Cycle Molding process was presented. Unlike the constant temperature boundary conditions in conventional injection molding simulation methods, the mold temperature was assumed to be variable in the filling process. The mold temperature in the heating process was first simulated. In the filling process, the flow equations were solved only on the cavity domain, while the energy equations were solved in a coupled manner for the cavity and mold domain at the matrix level.

Fabrication of microfluidic devices by soft lithography is by far the most popular approach due to its simplicity and low cost.

Here we describe an optimized replica molding approach to preserve the original masters by heat molding of polycarbonate (PC) sheets on PDMS molds.

Abstract:

Rapid thermal cycle injection molding technology with electric heating is a kind of widely-used and high-end injection molding technology; it can raise quality of plastic parts without reducing injection molding production efficiency. In the key technology of rapid thermal cycle injection molding with electric heating, the temperature control is the core technology. In this paper, we mainly design the temperature control system of small and medium size rapid thermal cycle injection molding with electric heating. First, give the temperature control parameters of mold, design the temperature con

Abstract:

Impact of product on the replication performance of mold cavity was tested and studied in the high-temperature rapid molding process based on high-fitness mold for in-vehicle Bluetooth module compartment cover. The results indicated that the main difference between high-temperature rapid molding and common molding is that when the mold temperature rises to around the plastic heat distortion temperature, the product’s reproduction rate of the mold cavity surface is improved significantly. In the area lower or higher than the plastic heat distortion temperature, the changes on mold temperature h

Abstract:

In injection molding processes for thermoplastic parts, the polymer solidification phase in the molding cavity has a strong influence on the quality of the shaped parts and also on the process cycle time. Reducing cycle time is one of the major concerns for plastic injection industries. As cooling phase presents the most critical phase to get quality and cycle time of the part, the application of additive manufacturing (AM) technologies has been overcoming the limitations of traditional cooling system design. AM enables the construction of conformal cooling channels for higher cooling uniformi

Abstract:

Three-dimensional heat transfer-curing simulation was performed for the curing process by introducing a large area compression molding for simultaneous forming and mass production for the lens and encapsulants in the LED molding process. A dynamic cure kinetics model for the silicone resin was adopted and cure model and analysis result were validated and compared through a temperature measurement experiment for cylinder geometry with cure model. The temperature deviation between each lens cavity could be reduced by implementing a simulation model on the large area compression mold and by optim
