Righteous Technologies Interview Questions and Answers

The density of PP (Polypropylene) is approximately 0.9 grams per cubic centimeter.

• PP has a relatively low density compared to other plastics.

• The density of PP can vary slightly depending on the specific grade and manufacturing process.

• For example, a common grade of PP has a density of around 0.9 g/cm³.

• The density of PP is lower than that of materials like PVC (polyvinyl chloride) or HDPE (high-density polyethylene).

Designing products for molds involves considering the mold material, part geometry, and production volume.

• Determine the mold material based on the product material and production volume

• Consider part geometry and draft angles to ensure easy release from the mold

• Design for uniform wall thickness to prevent warping and sink marks

• Add fillets and radii to reduce stress concentrations and improve moldability

• Use simulation software to optimize mold design and identify potential issu...read more

The density of ABS (Acrylonitrile Butadiene Styrene) is typically around 1.04 g/cm³.

• ABS is a common thermoplastic polymer used in various industries.

• The density of ABS can vary slightly depending on the specific formulation and additives.

• For example, ABS with higher levels of butadiene tends to have a lower density.

• The density of ABS is important to consider in applications where weight and volume are factors, such as in automotive parts or consumer products.

Edm stands for Electrical Discharge Machining, a process of shaping hard metals using electrical sparks.

• Edm uses electrical sparks to erode metal and create a desired shape

• It is commonly used in the manufacturing of aerospace and medical components

• Edm can be performed using wire or sinker machines

• The process is highly precise and can create complex shapes with tight tolerances

Production preparedness refers to the state of readiness of a production process to meet demand efficiently and effectively.

• Production preparedness involves having all necessary resources, such as materials, equipment, and manpower, in place to meet production targets.

• It also includes having contingency plans in case of unexpected disruptions in the production process.

• Regular maintenance of equipment and machinery is essential for production preparedness.

• Effective communicati...read more
