In plastic manufacturing, the cost of raw materials has a significant impact on overall manufacturing costs. In recent years, prices have continued to soar, and it is becoming increasingly difficult to secure profits with a system that relies on purchasing. Now is the time to review the use of raw materials themselves and change the profit structure from the manufacturing site.<\/p>\n

Reviewing raw material costs changes profit margins.<\/h2>\n

In plastics manufacturing, it is not uncommon for raw material costs to account for more than 50% of total manufacturing costs. Therefore, even a cost improvement of only 10 yen per kg,Profit improvement of several million yen per year can be expected.<\/span>.<\/p>\n

For example, if the annual usage is 500 tons, an improvement of 10 yen will directly lead to a cost reduction of 5 million yen. Reviewing daily costs is an important management decision that greatly affects profit margins.<\/p>\n

Current situation of rising raw material costs and structural problems<\/h2>\n

In recent years, the cost of plastic raw materials has remained high. This is due to a complex mix of external factors, including naphtha price fluctuations resulting from soaring crude oil prices, rising international transportation costs, and unstable exchange rates.<\/p>\n

For companies with a strong dependence on virgin materials and outsourced compounds, the impact of such raw material cost increases is immeasurable. Since it is difficult to gain the understanding of suppliers, it is also difficult to pass on the cost of raw materials to customers, resulting in a structural problem that puts pressure on profits. In a situation of \"just purchasing raw materials and using them,Difficult to control costs in-house<\/span>and strategic improvements will be difficult to achieve.<\/p>\n

Common examples of wasteful structures<\/h2>\n

At manufacturing sites, there are many cases where raw materials are not used properly, resulting in losses. For example, inability to make good use of recycled materials results in waste or lost products, and poor yields result in extra costs.<\/p>\n

AnotheUnstable formulation of fillers and additives, causing quality problems<\/span>In some cases, the cost of collection and reimbursement cannot be overlooked. If a complaint develops, the costs associated with recovery and reimbursement cannot be overlooked. In addition, there are some sites where additives are put in more than necessary and proper cost control is not achieved. All of these factors put pressure on the cost of raw materials for plastics and require immediate improvement.<\/p>\n

Redesigning raw materials to solve the problem<\/h2>\n

The breakthrough for profit improvement lies in reviewing the use of raw materials themselves. For example,In-house system for kneading and dispersion<\/span>by preparing for the redesign and reuse of purchased raw materials as a resource.<\/p>\n

Specific measures include cost compression through active use of recycled materials and high filler content, and quality stabilization through kneading and degassing using twin-screw extruders. Furthermore, switching from outsourcing to in-house design of material formulations will make it possible to achieve both cost and quality.<\/p>\n

Below are details on the raw material cost improvements that can be realized with twin-screw extruders.<\/p>\n

Material Strategies Enabled by Twin Screw Extruders<\/h2>\n

Twin-screw extruders are capable of performing a series of processes such as heating, shearing, kneading, and degassing, and are suitable for kneading raw materials to homogeneity. It has high kneading performance and dispersibility, enabling the use of low-cost materials and recycled materials that have been difficult to use in the past.<\/p>\n

In recent years, improvements in operability have made it possible for even small-scale, small-group factories to operate without difficulty, encouraging in-house production and independence in materials strategy.<\/p>\n

Uniform dispersion is achieved while efficiently degassing air and generated gases contained in high filler materials. This allows stable use of inexpensive materials such as wood powder and regrind materials without burning or color irregularities.<\/p>\n

For example, wood flour that has not been pre-dried can be converted directly into pellets. In addition to the reduction of equipment and energy costs by omitting the drying process,Increased freedom of raw materials<\/span>This will also help to optimize overall material costs.<\/p>\n<\/div>\n

HTM type tandem kneading extruder<\/div>\n

High kneading and degassing performance ensures stable extrusion and pellet quality while increasing the use ratio of recycled and high filler materials.<\/p>\n

Unique to recycled plasticsBecause water and gas components can be efficiently removed, physical property deterioration and burning are prevented even for recycled materials of unstable quality.<\/span>and can be used effectively as a material.<\/p>\n

This equipment expands the choice of available raw materials at sites such as chemical recycling, material recycling, and biomass kneading, resulting in optimization of raw material costs.<\/p>\n<\/div>\n
