Hence, there are various features that you should consider when choosing a silicone machine, and some of these factors include:

1. The Type of Silicone Machine 

The first factor to consider when choosing a silicone injection machine is the machine type because the design and engineering determine the machine’s functionality and performance. A good silicone injection molding machine will operate smoothly, efficiently, and reliably, leading to consistent product quality and minimizing downtime.

In addition, not all machines achieve the same level of precision, and some produce more units than others in the same period. So, considering the type of machine is essential because it determines the volume of silicone products you can produce in a given timeframe and the smoothness you will achieve on product edges. 

2. Check Silicone Machine’s Capacity

A silicone injection machine’s capacity is the highest product output it can produce in a certain period. This factor is crucial because it determines whether your chosen machine can meet your production demands without breaking down. 

Your machine’s capacity should not go below your market needs. Otherwise, you will run at a loss. Imagine if the market demand for your product is 15,000 pieces, but your machine’s capacity is only 100 pieces per week; that’ll be a massive loss to your company.

On the other hand, you’ll have excess supply if your machine’s capacity is way higher than demand. It’s wise to start with a reasonable capacity range and improve as your business grows over time.

3. Material-Machine Compatibility

We often focus on purchasing high-quality, sophisticated machines without considering other factors. One thing we often neglect is the material we will put in the machine for production. Each molding machine has a specific material fit for it.

Army attempts to use inappropriate and low-quality materials would result in multiple errors. There’ll be so many irregularities with the final product, not to mention the mechanical malfunctions it can cause to the machine.

The most common silicon materials among manufacturers are the Liquid Silicone Rubber (LSR) and the High Consistency Rubber (HCR). The HCR is widely used in the medical industry, while the LSR is more versatile and fit for electronic, electronic, industrial, and medical productions.

Properties like their low toxicity, durability, high tensile strength, and wide temperature range always make them a top choice. Irrespective of the type of material you choose, you need proper information on its properties.

To make your silicone product manufacturing products easier and faster, you’ll need silicone injection molding machines that use high automation functions. Features like the programmable logic controller (PLC) and Human-machine Interface (HMI) functional control systems ensure that you can input actions and return to roles that need more human input or simply sit back and let the machine work.

The PLC allows superb motion control by configuring the machine interface and creating multiple systems to control acceleration, deceleration, and machine speed with a simple button push. The HMI software links your machine control system with an input device. Combining these two features will automate your production process and reduce the wear and tear that comes with operating a manual silicone molding machine.

6. The Type of Hydraulic System

One indication of a good molding machine is an electronic, hydraulic system that allows you to navigate the machine and control the entire molding process with simple steps. It also offers you different operating modes to choose from.

One of such option is the servo motor, which rotates the silicon during molding and helps reduce production costs in the long run. With these options, you can easily configure the machine to suit your preference at any given time. You can either go full-throttle for maximum effect or go easy to conserve energy.  

So, before you settle on a molding machine, ensure you know the type of hydraulic system that drives it. Also, it’s easy to spot the hydraulic system; it is usually at the machine’s base.

7. Test the Silicone Mold Compatibility

Each molding machine is unique, with its distinct features, specifications, and designs. However, one thing remains constant: its efficiency in bulk production. Unfortunately, using an incompatible mold can thwart this feature.

One thing you must constantly check is the machine and mold compatibility. When there is perfect alignment, you’ll have a smooth production process instead of the many hitches accompanied by a misaligned mold.

8. High-Precision Silicone Machining

But why is precision important in the production of silicone products? It is necessary because it ensures that companies produce consistent silicone product quality.

This helps them avoid throwing away incorrectly designed silicone products or parts, which can waste resources and time. In addition, inaccurate production ruins the entire effort and can make you buy more raw materials that will be used to replace the ruined silicone products.

9. Plunger Feeding System 

Moving on, you should also check if the silicone injection molding machine has a plunder feeding system, especially if you’re mixing different materials in a mold. The system allows for precise control over the ratios of substances used during the manufacturing process. The plunder feeding system determines this by ensuring that the right amounts of materials are always mixed perfectly. 

10. Touch Screen Operation System

Silicone injection molding machines incorporating touchscreen technologies enable manufacturers to operate better and faster than those that don’t. These systems have a simple user interface, making them easily accessible. They are also highly durable, increase control and precision, and reduce staff costs. Also, most silicone machines with touchscreen features store previous mold settings, so there is no need to make new inputs often.
