Home Appliance Mould

What is Home Appliance Mould?

 

Home appliance mould also referred to as "electrical appliance mould," pertains to the production of plastic components for household electric appliances. These moulds encompass both the interior plastic parts and the external housing or casing.In the precision injection molding manufacturing of major appliances, a high-precision home appliance plastic injection mould is indispensable. The home appliance industry necessitates tailor-made plastic injection moulds suitable for insert molding, overmolding, or thin-wall molded products.

 

Advantages of Home Appliance Mould

Precision and accuracy

Home appliances often have intricate designs and precise specifications. Therefore, the molds used to produce their components must meet strict dimensional accuracy requirements to ensure proper fit and functionality.

Aesthetic standards

Home appliances are visible and often part of the decor in households. As such, the surface finish of molded parts must meet high aesthetic standards to maintain the overall visual appeal of the product.

Durability and longevity

Home appliances are expected to have a long lifespan, so the molds used to manufacture their components must be durable and capable of withstanding the high pressures and temperatures of the injection molding process over numerous production cycles.

Consistency and reliability

Home appliance manufacturers demand consistency and reliability in their production processes to maintain product quality and brand reputation. Injection molds must produce parts with minimal variation and defects to meet these requirements.

Design Points of Home Appliances Mould
 

Wall thickness design

The wall thickness of a plastic part is primarily influenced by its external dimensions and materials. However, in the design of plastic products, maintaining a uniform wall thickness is a fundamental principle. Deviations in wall thickness can lead to defects in the appearance of plastic parts, including shrinkage, depressions, deformations, and internal stress, ultimately resulting in cracks.

If the wall thickness is too thin, it can increase the resistance to the flow of molten plastic, impede material flow in the cavity, making it challenging to fill the material. This results in unfilled areas and compromised strength in the plastic parts.

Conversely, excessively thick wall thickness is not advantageous. It can lead to issues such as bubbles, shrinkage, depressions, and deformations in the product's appearance. Moreover, thicker products are heavier, increasing the overall cost. Additionally, thicker wall thickness prolongs molding time due to extended pressure holding and cooling times, resulting in lower production efficiency. However, when strength requires local thickness, a gradual transition between thick and thin is necessary to prevent abrupt changes.

Design of fillet and draft angle

The stress concentration at sharp corners in injection-molded cases can result in brittle failures. Eliminating sharp corners reduces stress concentration, reinforcing rib strength, and enhances the product's ability to withstand external impact. In the design of home appliances, outer arc corners should be maximized, avoiding excessive rounding transitions, typically maintaining an arc size range between 0.3mm and 0.8mm.

Drafting is crucial for smooth demolding during mold production. The draft angle depends on factors such as part size, wall thickness, shrinkage, and mold cavity surface roughness. Controlling the demoulding angle between 20' and 1°30' prevents difficulties in removing plastic parts due to shrinkage during continuous cavity shrinkage.

Reinforcing rib design

Reinforcing ribs enhance the structural strength of plastic parts, reducing the likelihood of warping, plastic consumption, product weight, and production costs without increasing wall thickness. In rib design, strict control of rib position, height, and even distribution helps avoid cold shrinkage at the rib bottom. Maintaining consistency between rib distribution and melt filling direction aids in the injection mold's opening and closing. Adopting an arc transition for reinforcing ribs and rounding corners at the bottom of ribs improves melt fluidity and reduces stress concentration. Typically, reinforcing ribs are around 50% to 70% of the wall thickness, with the r angle at the bottom being approximately 1/8 of the wall thickness.
