Precision Injection Molding
Precision injection molding is a method demanding unparalleled accuracy in shaping plastic components. Unlike mass production, it's reserved for cases where precise forms are crucial. These precise plastic parts are commonly used in replacing high-precision metal parts in fields like instruments, electronics, optics, and medical equipment. Due to these stringent requirements, precision injection molding relies on precise molds and machinery, making it a complex process.
The size tolerance of precision injection molds is controlled to less than 1/3 of the product size tolerance. The mold's precision depends on factors such as the accuracy of cavity size and quantity, cavity positioning, accuracy of parting surfaces, material selection, size tolerance, and more. Factors like the thickness of the base plate, support plate, cavity walls, and runner size are crucial for precision molds. The design engineering is equally vital, with molds typically made from high-strength alloy steel.
Precision Injection Molding Process:
Every component developed in precision molding projects must be identified, as their connection is uniform. This ensures a slow, stable, and concentrated precision molding process. The uniqueness of the process for each project emphasizes the importance of mold, part design, material selection, and procedures for successful precision molding.
Precision injection molding machines must control product accuracy and repeatability. The machine should feature a rigid clamping system, part size tolerance control, molding speed, and various components like the screw, screw head, barrel, and collar, all controlled within 0.05 to 0.08mm.
Precision injection molding is a game-changer for industries requiring high-tech, detailed, and complex parts in large quantities. WIT MOLD's expertise in design and manufacturing ensures a seamless experience in large-scale production. Embrace the precision for a future of cost-effective, efficient, and customized manufacturing.

Regarding with seafood industry, we started as fishing fleet company with 33 fishing boats as family owned business since 30 years ago. After establishment of our 1st frozen cooked tuna loin factory in 2002, expanded our manufacturing scope by establishing of new processing and cold storage facility at north sumatra in 2005 and exporting our owned processed indonesia origin frozen seafood (cuttle fish, squid, octopus, baby octopus, scallop, ribbon fish, conger eel, yellow stripe trevally, purple spotted bigeye, silver / yellow croaker, top shell, threadfin bream, lizard fish, goatfish, hard tail scad, spanish mackerel and long tongue sole) to Japan, Korea, Hong Kong, China, Taiwan, Singapore and Australia.

Rubber granules

Origin of the product :

Crushed tires resulting from the recycling of a mixture of used tires of various categories (pv, cv, gv, hgv, pwv, cev, iv, agrarian, handling, motorbikes, etc).

All the technical features of these tires comply with the regulations and standards requirements of france and of the european union.

The rubber is made of a mix - in variable proportions - of 2 main types of synthetic rubber and of natural rubber. The 2 types of synthetic rubber are :
- the sbr (styrene butadiene rubber)
- the nbr (nitrile butadiene rubber)

Apparent density :

482 kg/m3 or 0, 482 (adimensional).


Industrial process of manufacturing :

Exclusively with a mechanical crushing of the tires at ambient temperature.

The process used does not require and does not reject any kind of solid, liquid or gas additives.
