1. TPE (based on SEBS substrate)
Injection molding. The molding temperature is between 130 and 230 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding* or two-color injection molding.
Extrusion molding. The molding temperature is 125 to 220 degrees. Generally, the TPE material is extruded separately, or it can be co-extruded with other plastics.
Salivation molding. Use extruder, calender and other equipment to make TPE melt into a film with a thickness of 0.05~0.5mm. The calendering salivation temperature is 170~200 degrees. It should be pointed out that the salivation performance of TPE is not very outstanding.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is 170~200 degrees. There are few TPE models used for blow molding, because blow molding has higher requirements for the melt strength of TPE materials. Even if it is blow molding, TPE is only used to make blow molding products with thicker thickness and simpler structure. Pouring and pour molding. This generally applies to TPE with very low hardness. The TPE is melted with a heating device and called a high-temperature melt, and then the high-temperature melt is poured into a mold, and cooled and solidified to obtain a finished product. The reference melt temperature is 170~220 degrees.
2. TPR (based on SBS substrate)
Injection molding. The molding temperature is between 160 and 200 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding or two-color injection molding.
Extrusion molding. The molding temperature is between 145 and 200 degrees. Generally, TPR material is extruded separately, or it can be co-extruded with other plastics.
Salivation molding. Use extruder, calender and other equipment to make TPR melt into a film with a thickness of 0.05~0.5mm. The salivation temperature of calendering is 170~200 degrees. The salivation performance of TPR is average.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is 170~190 degrees. There are few TPR models used for blow molding, because blow molding has higher requirements for the melt strength of TPR materials. Even if it is blow molding, TPR is only used to make blow molded products with thicker thickness and simpler structure.
3. TPU (Thermoplastic Polyurethane)
Injection molding. The molding temperature is between 170 and 220 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding or two-color injection molding.
Extrusion molding. The molding temperature is between 175 and 210 degrees. Generally, TPU material is extruded separately, or it can be co-extruded with other plastics.
Salivation molding. Use extruder, calender and other equipment to make TPU melt into a film with a thickness of 0.005~0.05mm. The calendering salivation temperature is 170~210 degrees. TPU has excellent salivation performance. Many waterproof raincoats, luggage fabrics, etc. are made of TPU.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is 170~210 degrees. The blow molding performance of TPU is better than the TPE and TPR mentioned above.
4. TPV (Thermoplastic Dynamic Vulcanization Elastomer)
Injection molding. The molding temperature is between 180 and 210 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding or two-color injection molding.
Extrusion molding. The molding temperature is 170~200 degrees. Generally, TPV material is extruded separately, or it can be co-extruded with other plastics.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is 170~200 degrees. There are few TPV models used for blow molding, because blow molding has higher requirements for the melt strength of TPV materials. Even if it is blow molding, TPV is only used to make blow molded products with thicker thickness and simpler structure.
5. TPEE (Thermoplastic Polyester Elastomer)
Injection molding. The molding temperature is between 200 and 250 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding or two-color injection molding.
Extrusion molding. The molding temperature is between 195 and 240 degrees. Generally, TPEE material is extruded alone, or it can be co-extruded with other plastics. Salivation molding. Use extruder, calender and other equipment to make TPEE melt into a film with a thickness of 0.05~0.5mm. The calendering salivation temperature is 190~240 degrees. As a polyester elastomer, TPEE has excellent salivation performance.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is between 190 and 240 degrees. Polyester TPEE has high melt strength and therefore has good blow molding properties.
6. TPO (Polyolefin Thermoplastic Elastomer)
Injection molding. The molding temperature is between 180 and 220 degrees. Injection molding includes single-material molding and dual-material multi-logistics molding, or also known as overmolding or two-color injection molding.
Extrusion molding. The molding temperature is between 145 and 200 degrees. Generally, TPO material is extruded separately, or it can be co-extruded with other plastics.
Blow molding. Use an extruder to make a pre-blown embryo body, and then use a blow molding auxiliary equipment to blow the embryo body into the required shape size. The reference blowing temperature is between 180 and 210 degrees. Although TPO has good melt strength, for compound modified TPO, its blow molding performance depends on the compatibility of the compounding system components.
7. Rubber (thermosetting elastomer)
Rubber is a macromolecular elastomer with an amorphous shape, and generally requires vulcanization to exert its performance. The rubber processing technology and method are more complicated. Generally after raw rubber master mix-add other compounds (such as carbon black, antioxidants, synergists, etc.) to mix-add vulcanizing agent to mix again-make the required shape of the rubber part-put into the mold vulcanization. After the rubber material is mixed, it is processed and formed by a rubber injection molding machine, and the vulcanization is completed in the mold.
8. Silica gel (thermosetting elastomer) silica gel is divided into solid silica gel and liquid silica gel (LSR). Solid silica gel is generally used in industrial and daily necessities. The liquid silicone is used in medical and food tableware products. The solid silica gel is generally completed by a hydraulic press. The liquid silicone is completed by a special silicone injection machine.
