Profitable business model
Sales of recycled plastic pellets
This is a recycling business that crushes, heats, and kneads waste plastic to make re-pellets. As awareness of environmental issues grows worldwide, businesses that recycle waste plastics have been in the limelight in recent years. Among them is the sale of recycled plastic pellets by utilizing local industrial waste and other materials,Reduced procurement costs to ensure profits.is the appeal of this product.
In particular, when the price of crude oil rises, the price of virgin materials also rises in tandem, and pellets made from recycled plastic are expected to be in high demand.
Contract manufacturing of small-lot custom-made products
Contract manufacturing of plastics is the business of compounding and kneading according to the requirements of each customer. While many companies only handle mass production, being able to handle small-lot custom-made products is,It also differentiates us from other companies..
Furthermore, by utilizing a twin-screw extruder, it is possible to use the flexibility of mixing as an advantage. Another advantage of the twin-screw extruder is that it makes it easy to start a business on a small scale, without the need for large-scale facilities.
High-performance masterbatch production
Masterbatch manufacturing is the production of pigments and additives kneaded into base resins to add value to plastics. Pigments and additives are uniformly kneaded into the resin using a twin-screw extruder to provide products with a variety of highly functional properties such as antibacterial, flame retardant, and antistatic.
If we can provide a stable supply of high-function plastic products, it can become a highly profitable business with a view to developing our own brand. This is because the market demands technology and quality,This is an area where even small and medium-sized companies can compete.
Production and sales of bioplastics
In recent years, the bioplastic market using biomass-derived or biodegradable resins has been expanding globally in order to realize a sustainable society. In particular, materials such as PBAT, PLA, and PBS are attracting attention as alternatives to conventional petroleum-based plastics,Diverse applications such as food containers, packaging materials, and agricultural filmsThe adoption of this technology is progressing in the
In this field,Accuracy of temperature control and kneading control during processing is importantTherefore, the selection of appropriate equipment will determine the success or failure of your business. In particular, the use of extrusion equipment with excellent kneading and temperature control performance will enable the stable production of high-quality bioplastic products without compromising the characteristics of the material.
Main equipment required for plastics processing
Equipment required for plastics processing includes the following
| device name | role |
|---|---|
| Crushers / Pulverizers | Waste materials and raw materials are reduced in size and made reusable. |
| dryer | Essential for pre-processing of highly hygroscopic materials. |
| Mixers & Weighing Equipment | Adjust the ratio of additives, pigments, etc. to achieve uniformity. |
| extruder | The heart of the production line where raw materials are heated, kneaded, and molded. Available with a single or dual shaft. |
| pelletizer | Cut the extruded material into pellets. |
| Cooling and conveying line | Maintain product shape stability and quality. |
Each of these devices is directly related to process efficiency and quality stability, and all play an important role. Among them,Twin-screw extruders are attracting attention as core equipment that supports business differentiation by increasing the flexibility of materials.It is.
Why twin-screw extruders are key
Strong in high-mix low-volume production
Twin-screw extruders can freely reconfigure the screw configuration to perform a variety of processes. Therefore,Customization can be handled on a case-by-case basis.Another major advantage of twin-screw extruders is that they The ability to make materials suited to customer needs makes it easier to avoid price competition and to secure stable profits.
Works well with reclaimed materials
It is common for recycled materials to have variations in quality, such as contamination and deterioration. With twin-screw extruders, high dispersion reduces unevenness while,Stable processing even with recycled materialsIt is. Now that "small-lot production with design capability" is required rather than mass production, twin-screw extruders can be the key to differentiating our business in this context.
High kneading power
The twin-screw extruder allows pigments and additives to be uniformly dispersed throughout the resin by the interaction of the two screws.Less susceptible to variations in physical properties, even in complex formulationsThe feature of this system is that it is easy to maintain stable quality. It also contributes to the reduction of product complaints and realizes a highly reliable production system.
Actual use case: Small business succeeding with twin-screw extruder
Thailand｜Snack startup: Creating hit products in small quantities and in many varieties
A new snack company in Thailand has installed a small twin-screw extruder for food products to produce health-conscious rice puff snacks and corn snacks in a single unit. With a throughput of 350 kg per hour, the machine efficiently produces a wide variety of products in small quantities. The company captured the needs of the local market and achieved profitability in a short period of time.
Key Success Factors
- Flexibility to support multiple products with a single unit
- Automated processing of heating, kneading, and molding saves manpower.
- Ability to develop market-appropriate flavors and shapes
