#plastic prototype

Acrylic is one of the most commonly used plastics for machined parts in a variety of applications. Our acrylic machining includes CNC cutting, bending, mold thermoforming and surface finishing.

Rapid prototypes in the Automotive industry are key parts of the car development process. due to the long process of the automotive development cycle is a long process, the right prototypes could help the design team validate the design in the right direction at each critical milestone. Below we will introduce our related services.

Medical device prototype is created as early physical models of medical devices that aim to show how the product looks and operates.  It can allow designers and engineers to identify opportunities and risks in the early stages of the medical device design development phase. 

Urethane casting is a process that utilizes a two-part urethane resin to produce production-quality prototypes. it creates highly precise replicas of a master pattern. it is a cost-effective and fast turnround method for creating rapid plastic prototypes.

Urethane casting is widely used across industries like automotive, aerospace, medical, and consumer goods, particularly when intricate parts with complex geometries require low volume precise replication.

We have often seen two colors on a plastic prototype. Take the bottom of the phone, for example, the buttons are black but the number 5 is transparent. So how does that work?

Injection mold two times:

Two sets of molds are needed, and the processing process is as follows:

First, use a common injection molding machine to make transparent prototype number” 5”, then put the transparent prototype” 5” into another mold to injection the black material.in this way, the prototype will be two-color after out of the mold.

Two-color mold injection molding by two-color injection machine.

There are two back molds and two front molds. (The structure of the two front molds is the same.) Two rear molds are installed in parallel at the rear mold installation part of the prototype injection molding machine and two front molds are installed at the front mold installation part. The two-color injection molding machine has 2 nozzles (2 barrels), supporting 2 dryers, and 2 injection materials.

Injection molding process

After the first mold closed production, the number “5” of transparent material appear in the back mold. When the mold opens, the back mold rotates 180 degrees. (That is, the positions of the 2 rear modules are reversed).

After the second mold closed production, the black material injects cavity, surrounding the number 5. After opening the mold, we can see two color buttons.
