Our mission is to provide the best customer service and flexible solutions for our clients. Our staff is dedicated to that mission and our chief goal is to put the needs of our customers first.

Currently, our main services include:

The Customization of Silicone & Plastic Products

Part 1 Silicone Molding/Vacuum Casting Process

Step 1. Prepare the Master for Making the Silicone Mold

The master can be made from any stable material. Or it can be provided by the customer. In most cases, we make it via CNC machining or 3D printing.

Master materials are usually plastic or metal, which need to remain stable at 60-70℃ for a certain time.

Step 2. Make the Silicone Mold

The master is placed in a box and silicone is poured into it. It is then heated to 60-70℃in an oven until the silicone has completely cured.

After taking out the box from the oven, we cut the silicone into halves and remove the master. The silicone mold is ready with a shape as same as the master.

Step 3. Making the Parts via Silicone Mold

We can inject various compound materials into the mold according to your design requirements. To ensure that the replica is the same shape as the master, the mold is placed in a vacuum environment to remove air from the cavity and fill every area with liquid silicone.

After the material inside the silicone mold is cured and demolding, the part is ready.

Step 4. Doing the Surface Treatments

Sasanian offers a wide range of finishings to ensure that the part meets your expectations entirely. Our surface treatments include deburring, sandblasting, polishing, painting, drilling, tapping and threading holes, silk-screening, laser engraving, etc.

We also have a professional quality control team and equipment to inspect the parts to guarantee high quality.

Part 2 Plastic Injection Molding Production Process

Step 1: selecting the right thermoplastic and mold

Each plastic’s properties will make them appropriate for use in certain molds and components. The most common thermoplastics used in injection molding and their characteristics include:

Acrylonitrile-Butadiene-Styrene (ABS) – with a smooth, rigid and tough finish, ABS is great for components that require tensile strength and stability.

Nylons (PA) – available in a range of types, different nylons offer various properties. Typically, nylons have good temperature and chemical resistance and can absorb moisture.

Polycarbonate (PC) – a high-performance plastic, PC is lightweight, has high impact strength and stability, alongside some good electrical properties.

Polypropylene (PP) – with good fatigue and heat resistance, PP is semi-rigid, translucent and tough.

Step 2: feeding and melting the thermoplastic

Injection molding machines can be powered by either hydraulics or electricity. Increasingly, Essentra Components is replacing its hydraulic machines with electric-powered injection molding machines, showing significant cost and energy savings.

Step 3: injecting the plastic into the mold

Once the molten plastic reaches the end of the barrel, the gate (which controls the injection of plastic) closes and the screw moves back. This draws through a set amount of plastic and builds up the pressure in the screw ready for injection. At the same time, the two parts of the mold tool close together and are held under high pressure, known as clamp pressure.

Step 4: holding and cooling time

Once most of the plastic is injected into the mold, it is held under pressure for a set period. This is known as ‘holding time’ and can range from milliseconds to minutes depending on the type of thermoplastic and complexity of the part.

Step 5: ejection and finishing processes

After the holding and cooling times have passed and the part is mostly formed, pins or plates eject the parts from the tool. These drop into a compartment or onto a conveyor belt at the bottom of the machine. In some cases, finishing processes such as polishing, dying or removing excess plastic (known as spurs) may be required, which can be completed by other machinery or operators. Once these processes are complete, the components will be ready to be packed up and distributed to manufacturers.

One-Stop Sourcing Service

During the COVID-19 pandemic, many countries announced mandatory quarantine and have temporarily suspended their offline trading and business activities, but not all business activities can be suspended for an indefinite period. Global buyers still have to purchase industrial products and semi-finished products from China to continue production and to help their workforce return to work, but buyers cannot visit China during the pandemic due to the restrictions on international travel. However, Sasanian Trading can find qualified suppliers, ensure the safety of payment, and guarantee the safe delivery of goods purchased.
