Mold-Tech Texture Drafting Angle

By |December 18th, 2017|Categories: Design Develop Engineering, Mold Texture Specification, Surface finish standards|Tags: , , , , , |Comments Off on Mold-Tech Texture Drafting Angle

Mold Tech Texture Minimum Drafting Angle For Releasing(Demold) Injection mould tooling can be textured by different means, which may vary according to tool manufacture method, timescale, budget, material and supplier facility limitation. Aluminum tooling (and others) which is typically machined rapidly by a CNC process often uses bead, sand or vapour blasting to minimise budget and time. In practice, the final surface varies by supplier and can be influenced by the personal technique of the operator as well as the precise bead/abrasive material used. I've found it best to obtain moulded sample parts from the moulder/toolmaker in question, so that their specific process can be seen and approved, with their sample becoming the standard reference for all parties to abide by. Steel tooling, where spark erosion may be used to define final surfaces, can utilize the various textures available by the spark erosion/EDM techniques. Those are well defined and controlled by standards and applied by most suppliers. Guide plaques and reference strips are available for these and can be obtained from the machine manufacturers as well as other engineering supply houses/sources, Such sources can generally also supply polishing grading and gloss finish grading bars for other material finishes. These are commonly used to keep time and budgets tight. But sparking creates sharp cavities with a hardened [...]

SPI Mold Classifications & SPI Mold Standards

By |December 18th, 2017|Categories: Design Develop Engineering, Injection Mold Manufacturing, Injection Molding Technical, Mold Design Study|Tags: , , |Comments Off on SPI Mold Classifications & SPI Mold Standards

SPI Mold Classifications & SPI Mold Standards Society of the Plastic Industry Mold Building Standards The SPI Mold Classifications were developed by the U.S. Society of Plastic Engineers (SPE), with the intent of having a simplified definition of the type of injection tool for thermoplastics required for a set production need. These guidelines are intended to be just a reference that frequently further evolve, on a project by project basis or depending on the customer so that they better reflect what is required of a specific tool. The different classifications will dictate differences in tool design, construction, materials, and components. SPI Mold Classifications at UPMOLD UPMOLD provides SPI mold classifications from class 101 to 105 molds and Injection molding. We all pledge our best effort to satisfy our customer's needs regarding their expectations of quality, customer service, value, delivery and innovation. The following classifications are guidelines to be used in obtaining quotations and placing order for uniform types of molds. It is our desire through these classifications to placing order for uniform types of molds. It is our desire through these classifications to help eliminate confusion in the mold quote system and increase customer satisfaction. SPI MOLD CLASSIFICATIONS OF INJECTION MOLDS UP TO 400 TONS Customer is to approve mold design prior [...]

SPI Mold Unit Insert Standards

By |December 18th, 2017|Categories: Design Develop Engineering, Injection Mold Manufacturing, Injection Molding Technical, Mold Design Study|Tags: |Comments Off on SPI Mold Unit Insert Standards

SPI Mold Unit Insert Standards CLASS 1 UNIT INSERT 1. Detailed mold design required. 2. Insert retainer to be uniform hardness of at least 280 BHN. 3. All molding and/or functional details are to be made of tool steel hardened to at least 48 R/C. 4. Slides must have wear plates. 5. Temperature control provisions to be in cavities, cores and slides wherever possible. 6. Over the life of a mold, corrosion in the cooling channels decreases cooling efficiency thus degrading part quality and increasing cycle time. It is therefore recommended that plates or inserts containing cooling channels be of a corrosive resistant material or treated to prevent corrosion. 7. Parting line locks are required to be on all molds. 8. Insert retainers must have leader pins and bushings or some similar guidance system. CLASS II UNIT INSERT 1. Detailed mold design recommended. 2. Insert retainer to be uniform hardness of at least 165 BHN. 3. Cavities and cores must be 280 BHN or higher. 4. Water channels to be included. 5. All other extras are optional. CLASS III UNIT INSERT Can be constructed from aluminum, cast metal, cast epoxy or any material with sufficient strength to produce minimum prototype parts. Important: Refer to the general specifications to complete the details of this section, [...]

Injection Molding Part Design Guidelines

By |December 18th, 2017|Categories: Design Develop Engineering, Injection Molding Technical, Mold Design Study|Tags: , |Comments Off on Injection Molding Part Design Guidelines

Plastic Injection Molding Part Design Guidelines UpMold has provided these plastic part design guidelines because we strive to produce your molds and parts perfectly according to your designs. In order to assure that your parts are moldable, please examine the basic guidelines laid out on this page and follow these basic design steps when designing  your plastic parts. Injection Mold Wall Thickness by Resin Material Guidelines The proper material selection and observing uniform wall thickness in injection molded plastic parts, helps avoid potential issues such as sink marks and warpage. We recommended using the plastic part design guidelines in the table to the right as thicknesses vary by material: Material Available Wall Thickness(inches) ABS  0.045-0.140 Acetal 0.030-0.120 Acrylic 0.0025-0500 Liquid Crystal Polymer 0.030-0.120 Long-fiber Reinforced Plastics 0.075-1.000 Nylon 0.030-0.115 PC(polycarbonate) 0.040-0.150 Polyester 0.025-0.125 Polyethylene 0.030-0.200 Polyphenylene Sulfide 0.020-0.180 Polypropylene 0.025-0.150 Polystyrene 0.035-0.150 Polyurethane 0.080-0.750 Resin Available Wall Thickness(inches) Minimum acceptable wall thickness and layer height Overall wall thickness should be greater than or equal to the ideal amount, but thinner wall sections greater than or equal to the acceptable minimum are achievable. Wall thickness is geometry and application dependent. We recommend designing load bearing surfaces with ideal thickness or greater. Plastic part  of wall thickness and layer [...]

Injection Mold Cooling Design

By |December 18th, 2017|Categories: Design Develop Engineering, Injection Molding Technical, Mold Design Study|Tags: , |Comments Off on Injection Mold Cooling Design

Injection Mold Cooling Design In thermoplastic injection molding, part quality and cycle time depend strongly on the cooling stage. in this case we study some alternative cooling devices for the injection mold cooling design for core, The expected result is an improvement of the part quality in terms of shrinkage and warpage. Baffle, bubbler and thermal pin Baffles and bubblers are sections of cooling lines that divert the coolant flow into areas that would normally lack cooling. Cooling channels are typically drilled through the mold cavity and core. The mold, however, may consist of areas too far away to accommodate regular cooling channels. Alternate methods for cooling these areas uniformly with the rest of the part involved the use of Baffles, Bubblers, or Thermal pins, as shown above. Baffles A baffle is actually a cooling channel drilled perpendicular to a main cooling line, with a blade that separates one cooling passage into two semi-circular channels. The coolant flows in one side of the blade from the main cooling line, turns around the tip to the other side of the baffle, then flows back to the main cooling line. This method provides maximum cross sections for the coolant, but it is [...]

SPI Surface Finish Standards The SPI is that Society of the Plastics Industry  sets standard for plastics industry in the United States that identifies the cosmetic quality of plastics, Upmold uses  the SPI standard to define finish of plastic injection molded parts. There are twelve grades of finishes specified by the SPI in four categories that range from shiny to dull. Each grade has different requirements for allowable deviation from perfect, with lower numbers allowing for less deviation and higher numbers allowing for more deviation. Below specifications provide guidelines for mold surface finishes as provided by the UP MOLD.  For more information visit Tooling Manufacturing.
