The Role of Plastic Additives in Manufacturing
The use of plastics has deeply infused nearly every aspect of daily life, from packaging materials and medical equipment to household goods and automobile components. Plastics are highly versatile, primarily due to the ability to incorporate various additives that enhance their properties for specific applications. At Copar, we recognize the importance of understanding how additives […]
Nine Questions every client should ask before picking Mold Maker partner
When you’re getting ready to begin the injection molding process, the first choice you make—and one of the most crucial decisions—is which plastic mold manufacturing partner you’ll select. The partner you choose should, of course, deliver on all your mold requirements—but they should also prototype your part, help you with part design adjustments, warranty their […]
Mold Trial Production Operational Manual
Load the mold and: As per the material’s property and the mold tool size to choose the appropriate mold temperature controller to heat up the needed mold temperature. We need to check again all the movements of the mold after the mold temperature is up. If cycle time is too short, ejector pins will break […]
IBM vs ISBM
Bottle-shaped containers are molded by 3 processes: EBM (extrusion blow molding), IBM (injection blow molding) and ISBM (injection stretch blow molding). EBM is the oldest and least sophisticated of these processes. The following is a list of benefits and problems associated with ISBM and IBM produced bottles. Many users mix up Injection Stretch Blow Molding […]

How Everything Starts!?
Did you know? Jons Jacob Berzelius produces in 1847 first condensation polymer : polyester, derived from glycerin (propanetriol) and tartaric acid. Berzelius is also credited coining the chemical terms allotrope, catalysis, isomer and polymer. In 1865 Alexander Parkes was the first man made plastic by dissolving cellulose nitrate in alcohol and camphor containing ether. Resulting […]
In Mold Closing System “IMC”
In Mold Closing systems are used to automatically assemble molded parts prior to ejection from the molding surface. These systems operate during the opening time of the mold to minimize the impact on cycle time. Copar uses proprietary, proven IMC designs to integrate the closing rack and maximize mold cavitation. The closing arms provide precise movement […]
