Step.1 Order1. Confirm Order2. Issuer PI3. Provide Engineers with part drawings and special requirements

Step.2 DFMEADFMEA(Design Failure Mode & Effect Analysis ) should be prepared before the 2D tooling design ,which should include P/L, Gate location, Ejector pins and the basic structure of tooling as well as the comments for any parts design defects. This is a good way to save much time and cost for tooling design and fabrication.

Direct AnswerHow to maintain plastic paving grids over winter?Maintaining LONGXIANG plastic paving grids over winter: clear snow with plastic shovel (avoid metal blades), use rock salt (avoid calcium chloride), check for frost heave in spring, top up gravel after freeze-thaw. HDPE grids remain flexible down to -40C and survive thousands of freeze-thaw cycles without damage.Winter TipsSnow Removal...

Direct AnswerHow to choose the right plastic grid for driveway reinforcement?Choosing the right plastic grid depends on vehicle weight, soil type, traffic frequency, and aesthetic preference. LONGXIANG recommends 30-40mm grids for standard residential driveways and 50mm heavy-duty grids for commercial access. Key factors: grid height should match traffic load, and fill material should suit your c...

Direct AnswerAre plastic paving grids environmentally friendly?Yes, plastic paving grids are highly environmentally friendly. LONGXIANG grids are made from 100 percent recycled HDPE, fully recyclable at end of life, and their permeable design reduces runoff by 60-80 percent versus impermeable surfaces. They support grass growth, improving air quality and reducing urban heat island effect.Environm...

Direct AnswerHow to install plastic ground stabilization grids?Installing plastic ground stabilization grids involves 5 steps: excavate 100-200mm depth, compact sub-base, lay geotextile fabric, place and expand LONGXIANG grids, fill with gravel or soil or turf, and compact final surface. A 100m2 area can be installed by 2 workers in 1 day.Step-by-Step Installation1Site PreparationExcavate to requ...

Direct AnswerWhat are plastic paving grids used for?Plastic paving grids are HDPE-based geocells used for ground stabilization, permeable parking, driveway reinforcement, erosion control, and grass reinforcement. LONGXIANG supplies high-strength plastic grids that distribute loads over 200 tons/m2, prevent soil erosion, and allow 100 percent water permeability.Primary ApplicationsDriveway Reinfor...

Direct AnswerWhat Is Mold Flow Analysis and Why Is It Important for Injection Molding?Mold flow analysis (MFA) is a computer simulation technique that predicts how molten plastic will flow, cool, and solidify inside an injection mold before any steel is cut. It is critically important because it identifies manufacturing defects - such as warpage, sink marks, weld lines, and air traps - during the...

Direct AnswerHow to Reduce Injection Mold Manufacturing Cost Without Compromising QualityYes, you can reduce injection mold costs by 20-40% without sacrificing quality through five proven strategies: design for manufacturability (DFM), smart material selection, optimized mold design, early supplier collaboration, and production efficiency improvements. At Longxiang, our clients typically save 15-...

Direct AnswerWhat Are the Key Factors That Affect Injection Mold Quality and Lifespan?Injection mold quality and lifespan are determined by five primary factors: steel selection, heat treatment, mold design, precision machining, and ongoing maintenance. A well-designed, properly maintained mold from LONGXIANG can reliably produce 500,000 to over 2 million parts, while a poorly designed or maintai...

How Much Does a Custom Plastic Injection Mold Typically Cost?Custom plastic injection mold costs typically range from $3,000 to over $100,000, with the majority of standard production molds falling between $8,000 and $30,000. At Longxiang, a typical single-cavity production mold starts at $6,000, while complex multi-cavity or high-precision molds can reach $50,000–$100,000+. The final price depend...

Typical Lead Time for Custom Plastic Injection Mold FabricationFor standard custom plastic injection molds, the typical lead time ranges from 20 to 35 working days. At LONGXIANG, we deliver most standard injection molds within this window. For complex multi-cavity or high-precision molds, the timeline may extend to 45–60 working days, while simple prototype molds can be completed in as few as 10–1...

How to Choose the Right Steel Material for Plastic Injection MoldsSelecting the right steel depends primarily on production volume, plastic material (corrosiveness & abrasiveness), and surface finish requirements. At LONGXIANG, we guide clients through three main steel categories: pre-hardened (P20, 718H) for general-purpose molds under 500K cycles, through-hardened (H13, 420SS) for high-volume mo...

The DraftAngleAnalysis command visually evaluates surface draft-angle using false-color analysis.Draft angle is used to design injection-molded parts that must eject from molds.Steps1. Select objects.2. In the Draft Angle dialog box, set the angle for the color display.The draft angle depends on the construction plane orientation. When the surface is vertical/perpendicular to the construction plan...

With the definition of the parting plane and all necessary shut-offs,the core insert and cavity insert have been completely separated.To create the cavity and core inserts,the length,width,and height of the inserts must be defined.All of these requirements suggest making the core and cavity inserts as large as possible.For smaller molded parts,increasing the sizing the core and cavity inserts may ...

The important consideration should be end product and what your definition of "REGRIND" is. Reprocessing your own internal scrap (if kept clean and uncontaminated with anything else) is a significantly different question basis than using unknown or unclassified "regrind" from outside sources.As to the end ...

It's a small plastic injected piece that will be submitted to short period of time (2 seconds) of high temperature (95-105ºC approx.) in every cycle; this high temperature is produced by a filament where electric current passes through (like a house light bulb but hotter) for no mo...

Gate types The two main gate systems are manually trimmed gates and automatically trimmed gates. The following examples show where they are used:1. Sprue gate: Used for large components, the gate mark is visible in component and no runner is required. e.g.: bucket molding (backside ...

Ejection system types l Pin ejection—Cylindrical pins eject the finished component. In the case of square and rectangular components, a minimum of four pins (at the four corners) are required. In the case of cylindrical components, three equidistant pins (i.e. 120° apart) are requir...
