Flexible Gating Advantages, Dependable Reproduction, Economical Process, Easy to Maintain, Fast Molding Cycle, Decreased Tool Wear
SINCERE TECH is mold manufacturer china company that provides plastic mold making and plastic injection molding solutions to industries of the world, started since 2005 we specially make plastic molds for the customer, after 2016 we have bought a plastic injection molding company to mold the molded part for our world customers.
Our advanced manufacturing facilities include a wide range of thermoplastic injection molding solutions for many types of plastic parts, including processes for Hot Runner mold Systems and Cold Runner mold Systems.
Insulated Runner Molds: Hot Runner System With A Twist
Insulated runner systems are inexpensive alternatives to traditional hot runners, where the mold is not heated, but the runner channels are extremely thick and stay molten during continuous cycling.
This feature provides the flexible gating advantages of hot runner switch out the added cost of the manifold and drops of a heated hot runner system.
Properly designed insulated runners, with thermally controlled gate, offer several advantages over hot runner mold systems, including:
Dependable reproduction – no “dead spots” in mold
Uniform temperature distribution – thermal insulation forms through melt deposited at the wall
Economical process for continuous operation of uniform cycles without extended interruptions
Easy to maintain – quick to clean
Fast production color changes
Molds are less expensive to build and to maintain than hot runners
Minimal heat loss – thermal equilibrium reached quickly
Low energy input on startup – reduces energy cost
More consistent volume of polymer per part
Faster molding cycles
Elimination of runner scrap — less regrind
Mold manufacturer China
Improved part finish
Decreased tool wear
However, as with hot runners, the insulated runner system also has disadvantages when compared to cold runner systems. The increased level of technology required to manufacture and operate the mold results in:
More complicated mold design
Higher mold costs
More difficult start-up procedures
Possible thermal degradation of the polymer melt
More difficult color changes than with cold runners
