What is the material loss rate in injection molding, if 100 kg of material is purchased and only 90 kg is effectively used?
Consider the difference between purchased and effectively used materials.
Subtract the effectively used material from the purchased material and divide by purchased material.
This percentage would imply a larger material loss than actually calculated.
This rate suggests an even greater loss not supported by the numbers given.
The material loss rate is calculated as (100 kg – 90 kg) / 100 kg = 10%. This loss accounts for residues in the barrel, flash, and gate during injection molding.
Which equipment depreciation method results in different annual depreciation amounts?
This method allocates an equal amount each year.
This method accelerates depreciation, resulting in varying amounts each year.
This method bases depreciation on usage rather than time.
Though it accelerates depreciation, it differs from double declining balance.
The double declining balance method accelerates depreciation, leading to larger expenses in early years and decreasing over time, unlike the straight-line method which spreads costs evenly.
What is the primary reason to consider material loss rates in cost calculations for injection molding?
Consider the impact of leftover materials during the molding process rather than supply chain management.
Market price fluctuations relate to adjusting purchase prices, not material loss during production.
Material residues and waste occur during the injection molding process, impacting cost calculations.
Production time is more related to labor and machine efficiency than material loss rates.
Material loss rates are considered to accurately allocate costs associated with residues and waste generated during the injection molding process. This ensures the actual material usage is reflected in product costing, as opposed to only accounting for purchased material amounts.
Which method can be used to calculate equipment depreciation that affects product costs?
This method is typically used for averaging costs, such as raw material prices, not for depreciation.
This method spreads the cost evenly over the asset's useful life, impacting annual depreciation.
This method measures how often inventory is sold and replaced, unrelated to depreciation.
This is a financial analysis tool for understanding product costs, not a depreciation method.
The straight-line depreciation method is commonly used to spread an asset's cost evenly over its useful life. It directly impacts annual depreciation amounts and thus influences product costing by spreading equipment costs over multiple years.
What is the impact of material loss rate on injection molding costs?
Consider how unused material, such as residues in the barrel, contributes to overall costs.
Think about whether loss leads to spending more or less on materials.
Does losing material mean you use or discard less?
Does material waste directly relate to labor expenses?
Material loss rate increases the effective material cost because it accounts for the unused portion during production. This includes residues and waste, which must be factored into the product cost calculations to maintain accurate financial assessments.
Why is accurate working time statistics crucial in labor cost calculation for injection molding?
Accurate statistics help align labor costs with actual work done.
Consider whether time tracking directly affects material expenses.
Does accurate time tracking relate to efficient resource use?
Think about the relationship between time tracking and equipment valuation.
Accurate working time statistics ensure precise labor cost allocation by matching labor expenses with the actual hours worked. This helps in distributing costs accurately across different products and processes, thereby optimizing overall production efficiency.
What is the annual depreciation amount of an injection molding machine costing 500,000 yuan with a residual value of 50,000 yuan, using the straight-line depreciation method over 10 years?
Subtract the residual value from the purchase price, then divide by the lifespan in years.
This option neglects to account for the residual value.
This calculation might be based on incorrect years or ignoring the residual value.
This value likely results from a miscalculation of the initial cost and residual value.
The straight-line depreciation method involves subtracting the residual value from the purchase price and dividing by the asset's lifespan. Here, (500,000 – 50,000) ÷ 10 = 45,000 yuan annually.
Why is it important to consider material loss rate in raw material calculations during injection molding?
Material residues and wastage need to be accounted for in cost calculations.
The material loss rate does not directly influence production speed.
Energy consumption is measured separately from material calculations.
While important for cost, pricing involves more than just material loss rate.
Considering material loss rate ensures accurate cost allocation to products, as some material is lost in residues and waste. This impacts the overall cost of production but not directly other aspects like speed or energy.
Which method can be used to determine a reasonable material unit price when there are large price fluctuations?
This method averages prices based on different weights of importance or volume.
FIFO relates to inventory management and not directly to price averaging.
This is typically a depreciation method rather than a pricing strategy.
Another depreciation method, not used for price averaging.
The weighted average method accounts for fluctuations by averaging prices over time or volume. FIFO and depreciation methods like straight-line or double declining balance are unrelated to pricing strategies.
What should be considered when calculating material costs for injection molding?
Consider additional factors beyond just the purchase price.
This refers to the percentage of material lost during production.
Labor costs are separate from material costs.
While relevant, transportation fees aren't part of direct material cost calculations.
When calculating material costs, it is crucial to consider the material loss rate, which accounts for residues and waste during the injection molding process. This ensures a more accurate reflection of actual material usage and cost.
Which method can be used to determine a reasonable material unit price during price fluctuations?
This method averages prices based on the quantity purchased at each price point.
This doesn't account for quantities purchased at each price level.
This would likely inflate the material costs unnecessarily.
This may underestimate costs and lead to budget inaccuracies.
The weighted average method is used to calculate a reasonable unit price for materials with fluctuating prices. It considers both the price and quantity of materials purchased at different times, offering a balanced view of costs.
