What are the major factors affecting an injection Moulding process?
There are six major factors that remain critical to the plastic injection molding process.
1) Barrel Temperatures.
2) Plastic Flow Rates.
3) Plastic Pressure or "Screw Back" Pressure.
4) Nozzle Temperatures.
5) Plastic Cooling Rates and Times.
6) Plastic Melt Temperatures.
What type of process is usually best for high volume low variety manufacturing?
The correct option is: (b) Repetitive Focus. This type of focus is usually aimed at high production with repetitive, i.e., low variety results.
How do you increase production volume?
4 Strategies To Increase Your Production Capacity
#1 – Make the most of your space.
#2 – Improve your layout.
#3 – Increase output.
#4 – More storage capacity.
What are the types of capacity?
Capacity is defined under 3 categories; design capacity, effective capacity and actual capacity. The operations utilisation of resources and the efficiency of its processes can then be calculated using these.
What is capacity growth?
This ratio shows whether the business is capable of easily funding a higher turnover base. A positive result for this calculation indicates that the business should be able to fund its growth from additional profits; a negative result suggests that the business might experience liquidity problems if it grows.
Is batch production slow?
Because batch processing goes much slower, the overall cost of processing goes up. Starting up and using batch equipment can also increase energy consumption and the quality discrepancy between batches goes up. This can lead to lost production and compromised quality if the batch process isn't monitored closely.
How is injection molding machine capacity calculated?
Most injection molders will recommend 2.5 times the surface square inches of the part and an additional 10% as a safety factor. If you have a part that is 120 square inches, you would need a press size with 300 tons of pressure.
What wall thickness is commonly used?
The standard wall thickness for a residential house for 2×4 studs is 4-1/2 inches wide, including a 1/2 inch drywall on both sides. You should use 2×6 studs on walls with plumbing, which will bring the thickness to 6-1/2 inches, including the 1/2 inch drywall on both sides.
How do you produce production capacity?
Production capacity can be calculated based on a single type of product or a mix of products. The formula for production capacity is machine-hour capacity divided by the time it takes to produce one product.
What are the 4 types of facility layout?
Describe four major types of facility layouts: process, product, cellular, and fixed position.
