Plastic Refrigerator Drawer Injection Mold

Plastic Refrigerator Drawer Injection Mold

Mold Introduction

The PS Material of Refrigerator Transparent Drawer

Polystyrene (PS for short) is a colorless transparent thermoplastic made by free radical polymerization of styrene monomers, which has a glass conversion temperature higher than 100℃. As a result, it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

Polystyrene is easy to process and form, and has the advantages of transparency, low cost, rigidity, insulation and good printing. It can be widely used in light industry market, daily decoration, lighting instruction and packaging, etc. In the electrical aspect is a good insulation material and heat insulation insulation material, can make a variety of meter shell, lamp shade, optical chemical instrument parts, transparent film, capacitor dielectric layer.

What is Refrigerator Drawer Mold

The Refrigerator Drawer Mold or die refers to the tooling used to produce plastic parts in molding. Traditionally injection molds have been expensive to manufacture and were only used in high-volume production applications where thousands of parts were produced. Molds are typically constructed from hardened steel, pre-hardened steel, aluminum, and/or beryllium-copper alloy. The choice of material to build a mold from is primarily one of economics. Steel molds generally cost more to construct but offer a longer lifespan that will offset the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel molds are less wear resistant and are primarilly used for lower volume requirements or larger components. The hardness of the pre-hardened steel measures typically 38-45 on the Rockwell-C scale. Hardened steel molds are heat treated after machining, making them superior in terms of wear resistance and lifespan. Typical hardness ranges between 50 and 60 Rockwell-C (HRC).

Aluminum molds cost substantially less than steel molds, and when higher grade aluminum such as QC-7 and QC-10 aircraft aluminum is used and machined with modern computerized equipment, they can be economical for molding hundreds of thousands of parts. Aluminum molds also offer quick turnaround and faster cycles because of better heat dissipation. They can also be coated for wear resistance to fiberglass reinforced materials. Beryllium copper is used in areas of the mold which require fast heat removal or areas that see the most shear heat generated.

Refrigerator Drawer Mold Deisgn

*  The corner of PL need smooth without step and sharp.

*  Cavity have design two place inserts, it's easy for change.

*  4 pieces Spring used in cavity.

*  Lifter and hot nozzle have another water system, ensure the cooling enough.

Refrigerator Drawer Mold Assembly Process

1 . The design of Refrigerator Drawer Mold cooling system, pouring system and ejection system is reasonable

2 . The whole structure is compact, compact and reliable

3 . The overall processing is reasonable (less EDM in non-rubber parts), the assembly process is reasonable, and it is easy to replace (two thin steel parts are inserted, which is easy to replace).

Warpage analysis on DFM Report  

At Hongmei, we will analyze the potential warping issue on our DFM report. You are required to re-design your part design to avoid the issue or evaluate if it will affect final assembly.

Refrigerator Drawer Mold Assembly Principle

*  The precision of each part, such as distance dimension precision, coaxiality, equality, perpendicularity

*  Relative motion accuracy, such as transmission accuracy linear motion and rotary motion accuracy

*  Fit precision and contact precision, such as fit gap, interference volume contact condition, etc

*  The wall thickness of the plastic forming part. The wall thickness of the forming part should be at the lower limit of the dimension when the Refrigerator Drawer Mold is made.
