Melon Rubber is a leading manufacturer of liquid silicone rubber (LSR) injection molding with Innovative technology meeting custom injection molding, overmolding silicone o-ring, bellows, static seals, gaskets, membranes, septa, plugs, silicone-to-plastic bonded and silicone-to-metal bonded components, and more.

5 Advantage- LSR injection molding Capabilities- Custom Engineer Solution

1.High Production Efficiency with High Quality

High volume generally requires high production speed, which is the primary benefit of LSR injection molding. RFQ beginning, One of the first—but not always the most important—questions to ask is: How many pieces should be made?

for example,

like medical o-ring or flange gasket mould with 100 cav,

one daily capacitly by LSR injection molding is: 990 shots, meaning 99000pcs, basically no need for secondary trimming after liquid injection molding and import that there are no burrs, good quality,no need second trimming.

one daily capacity by silicone compression molding: 600 shots, meaning 60000pcs, be sure to arrange to trim after molding, remove the mold runner

Highest Precision, Special for Overmolding Silicone

The biggest question of overmolding silicone by compression molding is the positioning of the inserts. When the mold is closed, the manually placed rubber will shake, which will affect the molding of the silicone product and cause the problem of insert offset

Overmolding silicone by injection molding, which does not require manual processes such as compounding, mixing, cutting, and placing in the high-temperature rubber process. When the mold is closed, the A/B glue is directly injected into the mold cavity in liquid form, which is very good The packaged inserts can achieve high-quality customized overmolding silicone engineer solution

To create robust, pliable, high-precision, high-quality parts in large numbers as well as highly complex parts at lower volumes

Another major advantage of liquid molding is that the process imparts much more design freedom over conventional injection molding. Since the casting does not involve the use of high heat and pressures to initially melt the material so that it can flow evenly into the mold, the designer is not limited to maintaining uniform part geometry.

Perfect Way to produce custom silicone parts with undercutting, like bellow, mask

LSR injection molding and its special tool construction, which is possible and easy for molding and de-molding,

To avoid uneven wall thickness problems that may be caused by compression molding

Applications

LSR has a wide temperature range (-58°F to 392°F) &wide durometer range (10 – 80 Shore A), as well as liquid Silicone Injection molding parts that are highly water repellent and resistant. As such, coupled with the precise nature of their sizing, they’re ideal for use as seals, membranes, electrical connectors, and a variety of other medical, commercial and domestic applications.

Outside of its design, precisely how your product or part is molded has the greatest bearing on its cost and capabilities. Great ideas can founder taking the wrong course. So it is prudent to consider your options early in design.

How do you know when liquid molding ends and injection molding begins?
