Injection mold should not have too long heating time

Plastic injection mold some functions be strengthened. We call function refers to the size of its moisture absorption. However, this depends on what is the use of injection mold material. Nature of the material determines the level of performance. And the heating time after the issue also involved.
     
Injection mold because of the use of crystalline plastics absorb moisture relatively small, can not be preheated before molding, melt viscosity is small, the molding is not easy to break down, good flow properties, flow properties are more sensitive to pressure changes, a longer heating time prone to decomposition. So there should not be too long injection mold heating time for the production of products which play a limiting role. Because the production and manufacture of products will certainly be a set of rules were defined, so that it can form the best mold processing products.

What affects the quality of the mould?

Mold is closely related to our life, many things in our life are made by the mould.Injection mold is one of the mold, is a production of plastic products. Mould has its design requirements, acceptance criteria. There will always be some unqualified mould, this is why? what is the influence the quality of the mould?
1. Product structure: the optimization of product structure is the premise to realize mould quality, less failure factors
2. Technical requirements, accurate technical requirements is a important basis to make the mould acceptance standard.
3. Mold design, advanced mold design is to ensure that the mold a prerequisite for high efficiency and low cost.
4. Material parts: choose reasonable use steel and accessories is the key to ensuring mould long life use factor.
5. Process control, good process control is to ensure that the mold standard, an important means of mass production.
6. Mold manufacturing: high level of mold technology is the basis of manufacturing high quality mould components.
7. Try mould inspection: scientific test inspection method is a key link in the process of product manufacturing to meet customer demand.
8. Outbound acceptance: notarial outbound acceptance standard is the best judge the quality of mould delivery.
In order to the long-term development of the enterprise,WIT MOLD LIMITED plastic mold manufacturer adheres to pay attention to the quality of the mould.

WITMOLD professional manufacturing team

We know that a professional manufacturing team is essential to the high quality molds, so we emphasize a lot on the manufacturing team building. We are proud of that WIT MOLD have many professionals & skilled staff, with rich experience and much passion in plastic injection mold manufacturing. Here I would like to introduce part of our manufacturing professionals with you.
Let the team at WIT MOLD help to make your project a success.

Injection mold exhaust system design

Injection mold exhaust system to ensure the quality of the products forming plays an important role.
A, use of vent groove, vent groove is located in the cavity was full of parts, commonly exhaust trough depth vary with different plastic injection side shell, is basically not plastic produce flash to determine the allowed maximum clearance.
B, using the core insert putter fitting clearance door dedicated exhaust exhaust, mobile phone battery low pressure injection.
C, sometimes in order to prevent products vacuum deformation during ejection, will set gas pin.
D, sometimes in order to prevent products, design and simulation of empty adsorption device.

How to repair Plastic Injection Mold?

During plastic injection mold normal use, regardless of normal wear and tear or accidental will appear, you need to repair mode to solve.
1. Preparation mechanic dies after receiving the task
A, to ascertain the extent of mold damage;
B, referring to repair the master plate, analyze maintenance programs;
C, degree: We mold repair, largely without drawing conditions, while the principle of our service is "not affect the plastic parts of the structure, size", which requires us to mold repair technicians in the design size should be changed to acquire a good number of further next steps.
2, loading Chaimo Notes
A, labeled: When the repair technician to remove mold guide column, Division tube, thimble, inserts, briquetting, etc., especially requiring orientation, be sure to see the corresponding mark on the mold base, so that when the loading mode condemnation . In this process, take note of two things:
1) The identifier must be unique, can not repeat;
2) undeclared mold inserts, must be marked marked character;
B, foolproof: the wrong equipment parts appear to work and make a foolproof guarantee that the costume does not go upside-prone;
C, placed: demolition of parts required to neatly, screws, springs, rubber apron and other applications boxed well;
D, protection: The core, cavity and other precision parts should be placed on preventive measures, to prevent others from accidentally bumps.
3. Precautions when servicing Tattoos
A, province molding machine: When there are sticky mold plastic parts, such as the need to spend time dragging province mold, there are parts of the grain surface should be ready to protect before maintenance. Avoid mold machine province will Tattoos province light, uncertain requirements should fall in maintenance mode;
B, welding: If for Tattoos on welding, must pay attention to:
1) must be consistent with the mode CORE electrode material;
2) need to prepare tempering after welding work;
C, fill pattern: When china mold factory fill patterns need good maintenance and repair skin tissue are required to protect the grain surface, and indicate good grain fill sites, with fill patterns board. Etch back to the factory, you should carefully check the quality of etch surfaces before proceeding Die confirm OK. If the results hold for small repairs, you should confirm tryout OK, before the factory fill pattern.

The role of the strengthening rib injection mold

Formulate relevant china injection mould standard is in order to standardize mould processing, also can be more effectively regulate the unity of design and processing, improve the production efficiency of injection molding grinding tool.Plastic pieces of the proper setting of the strengthening rib can avoid the buckling deformation of plastic parts;Of material flow along the direction of the strengthening rib can reduce resistance in mold filling, liquidity melt, avoid air bubbles, the production of the phenomenon such as shrinkage cavity and depression.Strengthening rib in the plastic pieces of material flow guiding role when the battery to locate again at the same time, low profile 1 mm high score, the draft 2 degrees, at the top of the fillet, lower part chamfering R, width of 0.5 T.Usually the strengthening rib design principles for the height (too high easy son damaged under the action of bending and impact load), the width is small, and the number is good (plastic shape allows).
