How to optimize the mold to reduce weld marks? Use multi-point gates to shorten the melt flow distance (gate reconstruction); use trapezoidal or circular cross-section runners to reduce flow resistance and heat loss (runner optimization); add exhaust inserts to deep cavity molds to avoid air entrapment at weld marks (exhaust design); set heating plates at places where weld marks are likely to appear to extend the melt time.

Some people think that the fewer times of mold trials, the better the mold quality? In fact, the real value of mold trials is to discover mold design defects and adjust injection molding parameters. Through mold trials, potential problems such as product shrinkage, flash, and dimensional deviation can be exposed to avoid losses during mass production. The key to mold trials is not "less trials" but "one trial solves one problem."（Fewer mold trials ≠better mold quality）

How to avoid shrinkage of injection molded products? Remember 3 core principles1. The pressure should be "hard": Sufficient pressure and time are the key to offset shrinkage.2. The wall thickness should be "even": Uniform wall thickness design reduces shrinkage differences from the source.3. Cooling should be "fast": Fast and uniform cooling can solidify the surface and limit internal shrinkage deformation.

In injection molding, the purpose of heating first and then cooling is to optimize material properties and molding quality through temperature control. If the heating is uneven, the material may degrade and turn yellow, affecting performance. If the cooling is insufficient, the product will deform later due to residual internal stress.

Why is high-precision equipment so important for high-precision mold manufacturing? High-precision equipment ensures the accuracy of mold dimensions and surface finish, which is crucial to mold performance and product quality. Stable equipment can ensure the consistency of mold parts in mass production and avoid assembly problems caused by individual differences.

How to choose a mold injection molding factory for new product development? (Technology accumulation) We have mold designers with more than ten years of experience, which can help R&D avoid detours; (Equipment inventory) Injection molding machines of different specifications from 80 to 680 tons, CNC, EDM, and master craftsmen working meticulously; (Strong compatibility) Whether it is a standardized product or a high-requirement, high-precision complex product, we can cooperate with you.

Is the mold opening and closing not smooth? Quickly check in 3 aspects. Mechanical structure problem: Improper layout of the guide mechanism, inappropriate matching clearance, etc. will affect the smoothness of mold opening and closing. Parts wear: Wear of the slider, lifter, and ejector will cause movement obstruction. Installation error: Insecure installation or position offset will cause additional resistance during the opening and closing process.

Are plastic molds also classified into different grades? Level 1: Ultra-high precision, for aerospace, medical devices, etc.Level 2: High precision, used in medium-volume production like electronics casings and auto parts.Level 3: Medium precision, suitable for toys and daily plastics, cost-effective and efficient.Selecting the right mold grade ensures quality and cuts costs.

Are you worried that the mold size will be off? the quality will not meet the requirements? the delivery time will not meet the plan? Your problem should be solved by someone who understands the characteristics of steel materials, injection molding pressure, and your product scenarios. Choose GV MOLD to make the mold take fewer detours, get the product out of the circle earlier, and quickly turn creativity into reality!

Over-tightening the mold slider can lead to excessive stress on the mold components, causing deformation or damage. It may also increase friction, leading to premature wear and tear. Additionally, it can affect the precision of the mold, resulting in poor product quality and potential operational issues. Proper tension is crucial for maintaining mold integrity and efficiency.

There are two types of injection molding factories: one is mainly based on quantity, with large quantities and low prices, and focuses on efficiency; the other is mainly based on quality, specializing in high-precision products, balancing production capacity while giving priority to quality. Which type do you ask us? As long as you need, we can make your ideal type.
