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.

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.

They determine shape, accuracy, and mass production efficiency. Quality molds make great products! Follow GV MOLD for more manufacturing insights.

Why can't the clamping force be too high during mold trial? Too high clamping force will aggravate mold wear, causing defects such as flash and deformation on the product; it will also damage the injection molding machine, increase energy consumption, and increase production costs.

Excessive mold polishing can lead to several issues. It may cause the mold surface to become too smooth, reducing its wear resistance. This can result in faster mold damage and shorter service life. Additionally, it might affect the mold's dimensional accuracy, leading to product defects. Proper polishing is crucial to maintain mold performance and quality.

Do you know the depth of the venting groove of the injection mold? The depth of the venting groove is the key to balancing "gas discharge" and "preventing overflow". For general plastics such as PP and ABS, the depth is generally 0.02 to 0.04 millimeters. For engineering plastics such as PC and POM, the depth is generally 0.01 to 0.02 millimeters, and for thermosetting plastics, the depth is more than 0.07 millimeters. If the depth exceeds the limit, flash will occur, and if it is too shallow, air will be trapped.
