Quality

A major guarantee factor behind the products of our company is implementation of a comprehensive quality plan. Thanks to the constantly trained operational staff and utilization of the most advanced laboratory equipment, we are able to respect global standards in product quality assurance. Further, customers would also request for the lab services to fulfill their individual test requirements.

Product Engineering

The highlight of Jam Polypropylene Co.’s operation is the customer-oriented attitude and sustainability of relationship with customers that would be achieved through the products with high quality and technical assistance to the customers.
Establishment of an R&D center as well as a Technical Support Division, not only facilitates the improvement of available grades according to the customers’ needs, but also development of new grades with distinct characteristics.
The services we offer to our customers include consultation before the sales for choosing the most suitable grades according to their applications, provision of technical documents and after the sales for trouble-shooting, and solution-finding for downstream industries. We are also constantly moving through technical papers, scientific seminars and participation in international exhibitions towards the latest technical and commercial achievements.

Quality and Technology

Jam Polypropylene Co. has acquired the unique state-of-the art  Spheripol technology from Lyondellbasell,as the world leading technology for the production of a very wide range of polypropylene (PP) grades.
The fourth and fifth generations of Ziegler-Natta catalysts are utilized to provide a reliable flexibility in the production of polypropylene grade portfolio with premium quality, including impact and random copolymer grades along with the latest optimized grades through JPPC’s ongoing research.
A major guarantee factor behind the products of  our company is implementation of a comprehensive robust quality plan. Thanks to the constantly trained operational staff and utilization of the most advanced laboratory equipment, we are able to respect  global standards in product quality assurance.

Troubleshooting is the art and science of remedying defects after the process has demonstrated the ability to produce acceptable production parts. Most defects respond to one of a variety of process and/or material changes. The goal is to correctly identify which problem is actually causing the defect and to know when a particular solution will work. When making adjustments consider the following recipe:

• Create a mental image of what should be happening,
• Look for obvious differences,
• Make only one change at a time, and
• Allow the process to stabilize after any change is made.

Studies have determined that about 60% of defects result from machines and equipment, 20% from molds and dies, 10% from material, and 10% from operator error. Software programs, either already installed on the machine’s processor controller or available as a software package, can provide some help.
With all types of equipment, materials, and products, troubleshooting guides are set up (usually required) to take fast, corrective action when products do not meet their performance requirements. This problem-solving approach fits into the overall fabricating-design interface.
To understand potential problems and solutions (and eliminate myths), it is important to consider the relationships of machine and equipment capabilities, plastics processing variables, and product performances. A distinction has to be made between machine conditions and processing variables. Machine conditions could include operating temperatures, back pressures, screw rotation speed, die temperature, etc. Processing variables are more specific, such as melt conditions in the plasticator and die, melt flow rate versus temperature, etc.
When setting up troubleshooting guides, as well as reviewing any problems or even open discussions on the subject of fabricating, it is important that the terms used to identify a problem be understandable, clear, and properly defined.
Different terms are used throughout the industry to identify defects in plastic materials, fabricating equipment, and products. They include adhesive stringing, air bubble, applesauce, arrowhead, black speck, bleed, blister, blockage, bloom, blowhole, blush, burn line, chalking, coating defect, cosmetic defect, compressive buckling, crazing, degradation, electrostatic charge, fin, fines, fish-eye, flash, fracture, flaw mark, freeze-off, frosting, gas pocket, gel, globule, hairline, migration, orange peel, paint framing, pimple, pin hole, pit, plastic pocket, plate-out, pocket, pock mark, puckering, run, sag, scale, segregation, shark skin, sink mark, speck, splay mark, stain, starved area, streak, stress whitening, striation, surface finish, trim, void, weld line, yellowing, and so on.
