Injection Pepsi crate box mould

How to make high-quality turnover box molds?

A: Mould Design

Good injection crate mould design is the first step,PRC mould has 3 designers with more than 15 years experience.

1:We will analyze the feasibility,shrinkage and molding temperature of plastic products.
2 :We will communicate with customers,including details such as weight,style design,size and appearance,stability and wear resistance of plastic products.
3:Design and mold flow analysis are provided free of charge.

B: Mould Metal Material 

1:Choose different steel according to plastic product material,

mould life and customers requirements. 

2:We all buy mould raw material from large metal companies.
3:We personally test the hardness of the mould steel.
There are strict inspection procedures for the hardness of mould steel,

and mould life is 1 to 3 million shots.

C: Mould Machine Tooling 

1:After the injection crate mould drawing is confirmed,start production.
Including mold steel preparation, cnc rough machining, deep hole drilling, EDM,drilling machine,high-speed milling,finishing,polishing assembly,mold trial,electroplating,nitriding,etc.
2:Precisely control the size,and conduct self-inspection for each mould part according to the requirements of drawing size and tolerance limit control.

D : Mould Testing 

1:The first time test we do on the mold is to check that it moves smoothly and correctly.

After the crate mold is polished,we will test crate mould again,compare the test samples with the original design.

2:Then send the final samples and crate mold testing video to customers for confirmation.

E:Shipping Mould Details

1:The cavity and core are cleaned without iron filings and impurities.

2: We spray anti-rust agent on the inside of the mold,spray paint on the outside of the mould, and apply anti -rust oil on the thimble.
3: Mould parts are provided free of charge,(convenient for customers to replace).

4: Before the crate mold is shipped,we will check whether the opening and closing of the plastic mould is smooth,the water cooling system,the hydraulic oil system and the hot runner system.

F:Mould Maintenance Tips:

1: Routine maintenance of the mould:refueling of various moving parts such as thimbles,guide posts,and guide sleeves,cleaning the surface of the mold,and dredging accumulated water.

2: Regular maintenance:cleaning of exhaust grooves,discharge of trapped air and black spots,correction of damaged and worn parts.

3:  Appearance maintenance: spray paint on the outside of the mould to prevent rust. fixed mold and movable mould should be coated with anti-rust oil.when the mould is stored,it should be airtight to prevent dust from entering the cavity.

This is the whole crate mould project.

From product design to mould making,and then to the customer's factory to start producing plastic products.

Every step,we will invest a lot of energy and time to ensure the quality of the mould,make molds that satisfy

customers and gain customer approval,this is our target.
