Three Key Considerations When Choosing Blowing Molds

Blow molding mold is a combination plastic mold used for compression molding, extrusion molding, injection molding, plastic blow molding, and low foaming molding. Blow molding mold consists of concave mold combination baseboard, concave mold components, and concave mold combination card board. When selecting blow molding molds, there are several points to pay attention to. Let's take a look.


1. Do not only focus on product planning and ignore blow molding mold production


In the development or trial production of new products, some users often only focus on product research and development in the initial stage and ignore communication with blow molding mold production units. Early contact with the mold manufacturer after the product planning scheme is finalized has two advantages:


(1). It can ensure that the planned products have good forming processes, and will not make revisions to the finalized planning due to difficult-to-process parts.


(2). Mold manufacturers can make preparations in advance to avoid hasty considerations that may affect the schedule.


(3). Only when the supply and demand sides cooperate closely can we reduce the cost, shorten the cycle and make high-quality blowing molding molds.


2. Do not only look at the price, but also consider the blow molding molds quality, cycle, and service comprehensively


(1). There are many types of molds, which can be roughly divided into ten categories. Different types of molds should be selected according to different requirements such as part materials, physical and chemical functions, mechanical strength, dimensional accuracy, surface finish, service life, and economy.


(2). The mold with high precision needs to be processed by high-precision CNC machine tools, and has strict requirements on mold raw materials and forming technology, and also needs to use mold skills to plan and analyze.


(3). For some parts with special forming requirements, advanced processes such as hot runner, gas-assisted molding, and nitrogen cylinders are required in mold production.


(4). The manufacturer of blow molding molds should have CNC, EDM, wire-cutting machine tools and CNC copying milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer planning, and related software.


(5). Generally, for large stamping molds, whether there is pressure-edge organization in the machine tool needs to be considered, as well as edge lubricants, multi-station progressive, etc. In addition to considering the stamping tonnage, feeding equipment, machine tools, and mold protection equipment need to be considered.


(6). The above mold manufacturing methods and processes are not possessed and mastered by every enterprise. When selecting a cooperative manufacturer, it is necessary to understand its processing capabilities, not only paying attention to hardware equipment but also taking into account management level, processing experience, and technical capabilities.


(7). For the same set of molds, different blow molding mold manufacturers sometimes have a big price difference. You should not pay more than the value of the mold while also not paying less than the cost of the mold. Blow molding mold manufacturers, like you, need to gain reasonable profits from business. Ordering a set of molds with much lower quotes may start trouble. Users must weigh comprehensively based on their own requirements.


3. Prevent multiple collaborations and try to make blow molding and product processing Integrally


1) Having a qualified mold (with qualified trial parts) does not necessarily mean that mass-produced qualified products can be produced. This is mainly related to the selection of machining machine tools for parts, forming processes (forming temperature, forming time, etc.), and the essence of the operator's technical skills.


2) With good molds, good forming and processing are also necessary. It is best to have one-stop collaboration to prevent multiple collaborations. If the conditions are not available, one party must be selected to take full responsibility, which should be clearly written in the agreement.
