Details

At Jgoal Prototype, we specialize in high-quality custom plastic injection molding . Plastic injection molding is by far the industry’s most common way to manufacture plastic parts, especially when making larger quantities. We provide custom molding for 50 to 100,000+ injection molded parts as well as a wide range of other manufacturing and finishing services to complete your project.

Part production
 Resin pellets are loaded into a barrel where they will eventually be melted, compressed and injected into the mold’s runner system. Hot resin is shot into the mold cavity through the gates, the part is molded, and ejector pins facilitate removal of the part from the mold and into a loading bin. The thermoplastic injection-molding processes is a standard process involving an aluminum mold with no heating or cooling lines running through it, which means cycle times are a bit longer. It allows our molders to monitor fill pressure, cosmetic concerns and the basic quality of the parts, so they are ready to ship upon finishing. When the run is complete, parts (or the initial sample run) are boxed and shipped shortly thereafter.

Process
1) Storage
Two raw liquid material used in the RIM process were stored in two reservoir at certain temperatures, reservoir is commonly pressure vessel. In molding , stoste usually in 0.2 ~ 0.3 MPa low pressure in the reservoir, and circulating constantly in the reservoir, heat exchangers and mixing head. As for polyurethane, the average temperature of stoste is 20~40 ℃, the temperature control accuracy is ±1 ℃.
2)Measurement
Measurement will be finished by the metering pump , and requirements for measuring accuracy is at least be ± 1.5%, and the best control should at ± 1%.
3) Hybrid
In RIM process , product quality is largely depend on the quality of mixture in the mixing head , so does the production capacity . The normal pressure is about 10 Mpa in order to get the better effect .
4) Mold falling
The characteristic of RIM process is the material flow rate is very high .Then stoste’s viscosity can not be very high .Such as the viscosity of polyurethane mixture is about 0.1 Pa s.and flow rate control at 600 g/s in mold falling .
5) Curing.
Polyurethane two-component mixture have very high reactivity after injected in the mold ,so it complete curing in ten more minutes .But plastic’s conductivity is not good , so most heat can not release from a large chemical reaction condition , so that the outside temperature are higher than inside, so the curing development is from inside to outside .
6) Demold  
Demold also means we need release the cured part from the mold , and that part is the RIM product . And more quantity can be produced as the above process .
7) Post-Process  
It is according to customers’requirements .
